Quick start #

Install #

• latest version：install pub

Initialization #

initialization

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: HomePage,
      // here
      navigatorObservers: [FlutterSmartDialog.observer],
      // here
      builder: FlutterSmartDialog.init(),
    );
  }
}

Advanced initialization: configure global custom Loading and Toast

SmartDialog's showLoading and showToast provide a default style. Of course, custom param are definitely supported.

• SmartDialog custom Loading or Toast is very simple: However, when using it, it may make you feel a little troublesome
• for example
  • Use custom Loading: SmartDialog.showLoading(builder: (_) => CustomLoadingWidget);
  • The effect we want must be like this: SmartDialog.showLoading();
• In view of the above considerations, I added the function of setting custom default Loading and Toast styles at the entrance

Let me show you the following

• The entry needs to be configured: implement toastBuilder and loadingBuilder, and pass in custom Toast and Loading

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: HomePage(),
      // here
      navigatorObservers: [FlutterSmartDialog.observer],
      // here
      builder: FlutterSmartDialog.init(
        //default toast widget
        toastBuilder: (String msg) => CustomToastWidget(msg: msg),
        //default loading widget
        loadingBuilder: (String msg) => CustomLoadingWidget(msg: msg),
      ),
    );
  }
}

This is a very important function. I wanted to add it a long time ago, but it was busy and has been shelved; New Year's Day (2022.1.1) started, and it took some time to complete this function and related demos.
