Features

LoadingStatusButton is a Flutter package that provides an animated button with support for multiple states. It allows you to visually control the status of the button, including loading, success and error states, in addition to being able to leave the button enabled or not with status enable and disable.

Short example, for a more complex example go to the /example folder:

import 'package:flutter/material.dart';
import 'package:loading_status_button/loading_status_button.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Loading Status Button',
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        useMaterial3: true,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatelessWidget {
  MyHomePage({super.key});
  final LoadingStatusButtonController controller =
      LoadingStatusButtonController(initialStatus: StatusButton.enable);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SafeArea(
        child: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.spaceEvenly,
            children: [
              LoadingStatusButtonWidget(
                callback: () async => await fakeCallSuccess(),
                controller: controller,
                buttonColor: Colors.black,
                loadingColor: Colors.white,
                succesIconColor: Colors.green,
                errorIconColor: Colors.red,
                widget: const Text(
                  'Button Success',
                  style: TextStyle(color: Colors.white, fontSize: 17.0),
                ),
              ),
            ],
          ),
        ),
      ),
    );
  }

  fakeCallSuccess() async {
    await controller.setStatus(StatusButton.loading);
    //fake fetchData
    await Future.delayed(const Duration(seconds: 5));
    await controller.setStatus(StatusButton.success);
    await controller.setStatus(StatusButton.enable); // or another action, example navigate to another page after success
  }
}

If you want to remove this controller from memory, we can use the method inherited from ChangeNotifier, the method dispose

controller.dispose();
