Actually the pagination is outdated and can be simplified. Families weren't implemented at the time of writing.
I'll also include a "auto cancel HTTP requests if the request is no-longer needed by the UI" and some navigation.
from riverpod.
Ah good idea too
So:
- debounce on search (currently we have a search, just not denounced)
- retry
- pull to refresh
- offline
- cancel HTTP requests when no-longer-used
- data normalization
- deep-link to a character
That should keep me occupied for this weekend
from riverpod.
I opted for a separate list for the search bar
What do you think of it?
I like it as it demonstrate having two separate states in parallel - which is done by default with Riverpod's families
The main list is obtained with:
useProvider(characters(''));
And the filtered list with:
useProvider(characters(search));
from riverpod.
Good idea!
Any other things you'd like in it?

@rrousselGit Not really, debounce
is something that came to my head because I use it all the time on my projects (although relying on rxdart
).
The existing pagination example is very nice + the combination with freezed for the API responses.
I can't think of other common use cases at the moment.
from riverpod.
How about a Retry
on errors? As far as I can see the error would only be shown, without a way to get rid of it? Not sure how this fits into the pagination
from riverpod.
Saving state to disk and recreate the state when come back later :)
I wish there was a sync way to do it :(
from riverpod.
You could technically use File.writeSync
Do you want to though... Haha
from riverpod.
Uhhhhhh :D
class Foo extends StateNotifier<FooState> {
Foo(): super(FooState.fromJson(file.readAsStringSync()) ?? Foo())
}
from riverpod.
I'm honestly considering making a wrapper around a DB, such that we'd have:
final provider = StreamProvider((ref) async* {
final json = await ref.deserialize();
yield Value.fromJson(json);
}, name: "ID", serialize: (value) => value.toJson());
from riverpod.
off topic, but this sounds a bit like why I made https://github.com/hpoul/simple_json_persistence#usage-in-flutter-streambuilder which basically produces a json backed ValueStream.. only that you'd have call save
to update the state, instead of calling the setter..
from riverpod.
I updated the marvel example a bit.
I'm not done yet, but it's a pretty big simplification of how the pagination was done before
from riverpod.
Looking good. Can't wait to see how you solve reloading the character page on error :)
from riverpod.
Closing for now. The current example does include a denounced search.
I will implement the remaining points in different examples.
