📚 Veto

A lightweight MVVM state management solution originally inspired by the FilledStacks stacked package.

💡

The example project demonstrates every functionality of this package.

🛠 How to use it?

Create a view model.

import 'package:flutter/material.dart';
import 'package:veto/base_view_model.dart';

class VetoViewModel extends BaseViewModel<String> {

  int counter = 0;

  @override
  Future<void> initialise() async {
    debugPrint('''[🐛] [DEBUG] [🌟] [VetoViewModel.initialise] [📞] I was initialised!''');
    super.initialise();
  }

  @override
  Future<void> dispose() async {
    debugPrint('''[🐛] [DEBUG] [🌟] [VetoViewModel.dispose] [📞] I was disposed!''');
    super.dispose();
  }

  void increment() {
    counter++;
    rebuild();
  }
}

Create a view with the view model.

import 'package:flutter/material.dart';
import 'package:veto/base_view_model.dart';

import 'veto_view_model.dart';

class VetoView extends StatelessWidget {
  const VetoView({Key? key}) : super(key: key);
  static const String route = 'veto-view';

  @override
  Widget build(BuildContext context) {
    return ViewModelBuilder<VetoViewModel>(
      argumentBuilder: () => 'Test',
      builder: (context, model) {
        return Scaffold(
          body: Center(
            child: Column(
              mainAxisAlignment: MainAxisAlignment.center,
              children: [
                Text(model.counter.toString()),
                ElevatedButton(
                  onPressed: model.increment,
                  child: const Text('Increment'),
                ),
              ],
            ),
          ),
        );
      },
      viewModelBuilder: () => VetoViewModel(),
    );
  }
}

Enjoy MVVM! 😍

The entire package has extensive documentation. Reading the BaseViewModel class from top to bottom will give you a good idea of the benefits of this package. Also, a good example project, proper unit tests and some widget tests have been to illustrate and test the most important features of this package.
