Example

import 'package:flutter/widgets.dart';
import 'package:meshagent/meshagent.dart';
import 'package:meshagent_flutter/meshagent_flutter.dart';

class SampleWidget extends StatelessWidget {
  const SampleWidget({
    super.key,
    required this.room,
    required this.path,
  });

  final RoomClient room;
  final String path;

  @override
  Widget build(BuildContext context) {
    return RoomConnectionScope(
      authorization: (context) async {
        // Perform your authorization logic here
        // For example, you might want to fetch a JWT token from your server
        final response = await fetchJwtToken();

        return RoomConnectionInfo(
          url: response['url'],
          jwt: response['jwt'],
        );
      },
      authorizingBuilder: (context) {
        return Center(child: CircularProgressIndicator());
      },
      builder: (context, client) {
        return Text('Connection established');
      },
      doneBuilder: (context, error) {
        return Text('Connection ended with error: $error');
      });
  }
