Difficulty Accessing Bridge Classes When Loading Cross-Referenced Modules via sources in a Multi-Layer Flutter Project

[haxiaowei334]

This code is very practical and well-designed.

In a Flutter project, if my business logic code is organized into multiple layers and folders, how can I convert this code to be dynamically delivered? For example:

#code/app.dart

import 'package:flutter/material.dart';
import 'package:flutter_d4rtcoder/code/theme_controller.dart';
import 'package:flutter_d4rtcoder/code/app_theme.dart';
import 'package:flutter_d4rtcoder/code/complex_app.dart';

class MyApp extends StatelessWidget {
  final ThemeController _themeController = ThemeController();
  MyApp({super.key});

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return ListenableBuilder(
      listenable: _themeController,
      builder: (context, child) {
        return MaterialApp(
          title: 'Flutter Run Example - Advanced Theming',
          debugShowCheckedModeBanner: false,

          // Light Theme Configuration
          theme: AppTheme.lightTheme,

          // Dark Theme Configuration
          darkTheme: AppTheme.darkTheme,

          // Theme mode (controlled by ThemeController)
          themeMode: _themeController.themeMode,

          home: ComplexApp(themeController: _themeController),
        );
      },
    );
  }
}

#code/screens/detail_screen.dart

import 'package:flutter/material.dart';

class DetailScreen extends StatelessWidget {
  final String item;

  const DetailScreen({super.key, required this.item});

  @override
  build(context) {
    return Scaffold(
      appBar: AppBar(title: Text(item), backgroundColor: Colors.deepPurple),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Icon(Icons.info, size: 64.0, color: Colors.deepPurple),
            SizedBox(height: 16.0),
            Text('Details for $item', style: TextStyle(fontSize: 24.0)),
            SizedBox(height: 32.0),
            ElevatedButton(
              onPressed: () => Navigator.of(context).pop(),
              child: Text('Go Back'),
            ),
          ],
        ),
      ),
    );
  }
}

In InterpretedWidget, I only keep the entry class assigned to the code parameter, while other dependent classes are assigned through the sources parameter. However, I’ve encountered an issue: “The modules loaded through the sources parameter cannot correctly access the bridge classes,” because in the original project, these classes have cross-references.

I’d really appreciate any insights or suggestions on how to handle this situation gracefully. Thank you in advance for your time and help!
