Any chance to enhance the tags to accept objects in the context?
Something like (similar to your introductionary example):

class User {
    final String name;
    final String email;
    final List<String> roles;

    // constructor
}


List<User> users = List();
// add some users
context.variables['users'] = users;
final template = Template.parse(context, Source.fromString(raw));
print(template.render(context));

This would greatly simplify my code.

For example, I have HTML:
<button onclick="{{doSomething}}">Click Me!</button>
and Dart code:

void main(){
  //main function
}

doSomething(){
  //Do something
}

How am I supposed to achieve this effect?

contains for condition in if not working
eg;

string = 'hello world'

{% if string contains 'hello' %}
'bye'
{%else%}
'hello'
{% endif %}

expected o/p : bye
current o/p : hello

Hi,

the plus Filter does not seem to work:

{% assign we = 33 |plus: 22 %}

Error

E/flutter (25024): [ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: Parse Exception: Unexpected Token: <TokenType.identifier line=1 column=19 value='plus'> expected null

I wanted to implement the regroup tag in my project since it is missing in the builtin tags. Unfortunately I am not able to create tags in my project because a couple of classes are not exposed. These are: Expression, Tag, Token, TagParser, TokenType, Parser, ParseException.
There may be other necessary classes but for my first try that's it. Please make them available.

The package currently depends on dart:io, which prevents it from running on the web. Please remove this dependency or make it optional.

Hi,

I get an error when variables are assigned in a loop. This works with other liquid engines, is it possible to fix that?

Minimum example which causes the error:

{% for row in test %} {% assign a = 34 %} {% endfor %}

Error

E/flutter (25024): [ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: Parse Exception: Unexpected Token: <TokenType.identifier line=10 column=7 value='endfor'> expected null

Thanks,
Sebastian

I was trying to get list length by doing

<b>Total Users {{ users | length }}</b>

and also by doing

<b>Total Users {{ users.length }}</b>

but none of them worked!
