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(
        //custom default toast widget
        toastBuilder: (String msg) => CustomToastWidget(msg: msg),
        //custom default loading widget
        loadingBuilder: (String msg) => CustomLoadingWidget(msg: msg),
        //custom default notify widget
        notifyStyle: FlutterSmartNotifyStyle(
          successBuilder: (String msg) => CustomSuccessWidget(msg: msg),
          failureBuilder: (String msg) => CustomFailureWidget(msg: msg),
          warningBuilder: (String msg) => CustomWarningWidget(msg: msg),
          alertBuilder: (String msg) => CustomAlertWidget(msg: msg),
          errorBuilder: (String msg) => CustomErrorWidget(msg: msg),
        ),
      ),
    );
  }
}

• SmartDialog supports default global configuration

SmartDialog.config
  ..custom = SmartConfigCustom(
    maskColor: Colors.black.withOpacity(0.35),
    useAnimation: true,
  )
  ..attach = SmartConfigAttach(
    animationType: SmartAnimationType.scale,
    usePenetrate: false,
  )
  ..loading = SmartConfigLoading(
    clickMaskDismiss: false,
    leastLoadingTime: const Duration(milliseconds: 0),
  )
  ..toast = SmartConfigToast(
    intervalTime: const Duration(milliseconds: 100),
    displayTime: const Duration(milliseconds: 2000),
  );

Easy usage

• toast usage💬

SmartDialog.showToast('test toast');

• loading usage⏳

SmartDialog.showLoading();
await Future.delayed(Duration(seconds: 2));
SmartDialog.dismiss();

SmartDialog.show(builder: (context) {
  return Container(
    height: 80,
    width: 180,
    decoration: BoxDecoration(
      color: Colors.black,
      borderRadius: BorderRadius.circular(10),
    ),
