dash_chat's Issues

backend integrations?

Hi!

This is an awesome initiative.

Is anybody working on some backend integration already, for example if this package could connect to https://zulipchat.com/api/ it would be gold!

Horizontal overflow occurs when message content is too large

• Message row overflows text reaches a certain length
  • Occurred with avatars visible

My code using dash_chat

Message not sent by hitting action keyboard

Describe the bug
We don't have any way to send the message by hitting the keyboard action, neither to configure it to "send" action. Would be very nice to be able to do it

To Reproduce
click keyboard action, keyboard just close but message is not sent

Expected behavior
Message is sent

new message chat content not scroll to latest

Describe the bug
when have new message chatbox content not scroll to latest is freezing

When message too long

When message too long, it will show as follow

dash_chat producing an error when i tried to run the program

Thanks for the lovely plugin.

I downloaded the project and while trying to run the project on my computer, I received an error message and the project did not complete.

This is the error message

messageContainerPadding does not work

Setting messageContainerPadding to any value doesn't seem to work. I think this is because in message_list_view.dart I see this (line 39) this.messageContainerPadding = const EdgeInsets.only(top: 10.0, right: 10.0, left: 10.0),

I think the padding is always set to this const value vs being set to a value passed in

Overflow exception

Describe the bug
There is an overflow exception when the chat doesn't take the full width of the screen

To Reproduce
Use chat dash in master detail view and send a very long message

Expected behavior
Not having overflow

Screenshots

On inverse and sending a message the list scrolls to the top

as described and shown in the discussion #35 im assuming the issue is from this line https://github.com/fayeed/dash_chat/blob/master/lib/src/chat_view.dart#L386 , will try to implement a fix soon

Support multiple images

Currently, ChatMessage only supports one image URL. Please add support for adding more than one image URL.

This is not a bug, I just do not understand how to replace the default sendButtonBuilder

I was using the example and everything is working flawlessly, but then I try to change the default icon send but it ask for a specific time and I am not sure on how to create a type Widget Function(Function)
Could someone illustrate me. I do not need to modify the functionality, just the icon colors.

message item builders should give the full message object

Is your feature request related to a problem? Please describe.
My use case was just to add message status "sent, received, seen" to the message bubble, my idea was to use the messageTimeBuilder to add time and message status. Problem is that I don't have the message data on that builder so I can't retrieve my message status. So I had to redo the all message widget with messageBuilder instead. Work but much more stuff to take care.

Describe the solution you'd like
all message builders should give the full message object instead of just the information that the default widget is showing.

Emoji's have a blue tint

Emoji's have a blue tint. It is as if they are rendered behind a blue filter. It would be ideal for them to be rendered without this blue colour.

Steps to reproduce:
Create a chat.
Send a message containing an emoji.

Is there any away to show label for days ?

Hi fayeed,
I need show a label for date messages like whatsapp from firebase.
june1
message1,
message2,
message3
june2
message1,
message2,
message3,

List<DocumentSnapshot> items = snapshot.data.documents;
         var messages =
             items.map((i) => ChatMessage.fromJson(i.data)).toList();

How would i do that ?

Scroll to last index

The current implementation displays the first message then jumps to the last message. This breaks the user's focus and seems buggy but it's not. How can I prevent this and always show the latest messages. I've done this in a custom chat app but this plugin saves a lot of time.

check out the unwanted behavior here: https://1drv.ms/v/s!AqyIwuPueLgbq36o4gxQSomsZy3o?e=9HmIFr

Getting this error when trying to implement

Cannot hide avatars

Hey,

I have been working with dash_chat now for a while, however, I am not able to show deactivate the avatars for all users. Right now the avatar is always shown for one user. Although I set showAvatarForEveryMessage and showuseravatar ar both set to false. It seems that this behavior is not supported at the moment? Can someone confirm this?

dateFormat not working

The dateFormat attribute of the DashCat widget doesn't appear to affect the date headers

Add onShow(message) callback for each message shown on chat or a way to determine a Message was shown

Is your feature request related to a problem? Please describe.
I am currently struggling with how to display a Badge on the chat to indicate how many
unread messages are there. I am wondering if it is viable to add a hasShown property
in ChatMessage class? Does it make sense?
Or add a callback onShow(message) to DashChat so that we can track it ourselves?

Describe the solution you'd like
A way to track whether a ChatMessage has been shown.

Describe alternatives you've considered
With a callback onShow(message) to DashChat, we can track it outside of DashChat.

Additional context
Great plugin, really appreciate it.

Don't show padding on left side

Is it possible to show all messages on the left without padding when I don't show an avatar?

Displaying the current user messages on the right hand side

How can I display the message of the current user on the right-hand side of the screen? I see it on your demo but can't find a way to implement it.

Ask a question about the display location of the message content

Ask a question about the display location of the message content, the message is either displayed on the left or on the right, but I don't see the parameters related to the control of this location, do the following test, just swap the uid of the following two messages, the location of the message is also interchanged, the trouble tells you how to control the display location, Or what the rules that control the location are, thank you very much.

`

ChatMessage message1 = ChatMessage(
text: "Hello",
user: ChatUser(
name: "Fayeed",
uid: "2262561",
),
createdAt: DateTime.now(),
);

ChatMessage message2 = ChatMessage(
    text: "Hello2",
    user: ChatUser(
      name: "Fayeed2",
      uid: "123456789",
    ),
    createdAt: DateTime.now(),
);

[feature] add actions to messages

Current I am implementing a chat that requires a button in some chat bubbles for example (open settings) all some other features.

I was thinking of having at the bottom of a message a button bar that renders action if they are present, I can create a PR soon, any suggestion on what should be implemented with it?

scrollToBottom widget remains visible after leaving chat page

I am using package version 1.0.15 and it seems the problem is back. The scrollToBottom widget stays on top of everything even when I leave the chat screen.

This is the same problem that was brought up in issue: #4

I am using:

dash_chat: ^1.0.15

Make the "Scroll to Bottom" button optional

Really love what you've done here. Would be very nice if one could make the scroll to bottom button optional. Thank you!

Static Input Bar

Is your feature request related to a problem? Please describe.
Right now when using Dash Chat the input bar scrolls away when scrolling through the chat. Most chat systems today have a static chat bar so you can start typing while looking at other chats. I also get frustrated when using the current input bar because it has padding/margin issues when working on iPhone or if I want a bottom navigation bar under the input.

Describe the solution you'd like
A static input bar that will lock to the bottom of the screen (also with adjustable padding and margin) or an option to completely hide the built in input bar and hide our own.

Describe alternatives you've considered
I have not been able to find a solution directly to the problem regarding having a bottom navigation bar with the chat system. I do understand this is normally not ideal anyway but is necessary for an application I am building.

Additional context
I plan on implementing this myself and will submit a pull request. I will try and make this optional so it can be compatible with old projects.

Input footer hidden on keyboard popup

the widget inside the input footer are hidden when virtual keyboard is active

inputFooterBuilder: () {
return Column(
children: [
Text('asd'),
Text('asd'),
Text('asd'),
Text('asd'),
Text('asd'),
Text('asd'),
],
);
}

ChatMessage not cleared after calling onSend

After submitting a new message (onSend), the widget does not reset the state of the send button and will continue to send the last text entered every time it is clicked

ChatMessage() with onTap

ChatMessage() does not have the onTap() event, it is important for a message like localization that needs to open the map.

Ability to @mention

Is your feature request related to a problem? Please describe.
I would like to be able to @mention people in chat. This may be overkill for a drop in solution but would be very nice to have.

Describe the solution you'd like
When '@' is typed to prompt a list (can be provided to dash chat constructor) of Chat Users and as more letters are typed filter by the display name. Also make these names clickable in chat and bolded.

scrollToBottom

Describe the bug
Hello again Fayeed.
I really liked the UI, so I don't want to abandon it. But I have a problem.

How can I disable scrollToBottom ?

 return DashChat(
                  key: _chatViewKey,
                  user: user,
                  scrollToBottom: false,

When set scrollToBottom to false, nothing happens, the button keeps appearing;

Why am i wanting this?
Because when sending messages, sometimes a bug happens and it can't go to the bottom of the automated scroll.
And The distance it disappears from the footer is too short and I couldn't adjust this part.

When the keyboard is open and I send a message, the scroll does not reach the end.

If there is any way to get the down button only halfway up the screen, it would be ideal for me.

Thank you for your attention.

Scroll problem.

      );
  
      final msg2 = ChatMessage(
        text: "Test",
        user: user,
        createdAt: formattedDate("2020-04-02 00:00:00"),

ChatUser toJson throws invalid Argument error for Color properties

Describe the bug
When saving a chat message into the Firebase database an invalid argument error is thrown: "Invalid argument: Instance of 'Color'". This is because the 'containerColor' and 'color' properties of the chat user class are stored directly into the map without conversion to String.

To Reproduce
Steps to reproduce the behavior:

1. Go to the example code of dash chat
2. Extend the ChatUser user with properties for color and containerColor
3. Try to submit a new chatMessage to firebase by invoking the chatMessage.toJson() method
4. See error "Invalid argument: Instance of 'Color'"

Expected behavior
Please refer to this StackOverflow link in order to see how Colors should normally be treated in a JSON format: https://stackoverflow.com/questions/58812802/how-to-store-and-retrieve-color-from-firestore-in-flutter.

end
end
2. Open your app
3. The bottom of the chat will be hidden.

Load Earlier gap customization

Is your feature request related to a problem? Please describe.
Currently there is a 100px tall container that causes a wide gap between the start of the messages. Ideally this should be customizable as I want the latest messages to be a little closer to the app bar.

Describe the solution you'd like
Ideally a new property called "loadEarlierSpacerHeight" that can be customized with a value.

Describe alternatives you've considered
Either forking the project and making the change or trying to use some overly clever Stacks/Transforms.

If this doesn't make sense I can send along a code snippet!

E.g.

Adding a way to see message context in the message builder

Is your feature request related to a problem? Please describe.
I would like to display messages with a custom avatar and message, where the actual message bubble is different if it's followed by another by the same user (ie. in iMessage where there is a tail on the bubble unless the user sends a message right after). This would also allow me to display my custom avatar only once for each block of messages.

Describe the solution you'd like
A simple flag saying whether this message is followed by (and maybe one if it is preceded by) a message from the same user.

Describe alternatives you've considered
This could be on the message object, or as another parameter to the message builder.

We think that the problem is you use the default scrollController in chat_view.dart (initState) instead of our scrollController.
