class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    /// child should be [MaterialApp] or [CupertinoApp].
    /// make sure that loading can be displayed in front of all other widgets
    return FlutterEasyLoading(
      child: MaterialApp(
        title: 'Flutter EasyLoading',
        theme: ThemeData(
          primarySwatch: Colors.blue,
        ),

It works, thank you!

[genius1212]

The problem still exists,
It will appear in the timer
//
_timer = Timer.periodic(Duration(seconds: 1), (Timer timer){
EasyLoading.showToast('Toast');
_timer?.cancel();
});

@huangjianke
When the toast is in the Timer, it makes an error

That’s great!

[robertcsouza]

you need put in main builder: EasyLoading.init();

MaterialApp( title: 'Flutter Demo', initialRoute: '/', routes: routes(), builder: EasyLoading.init(), theme: ThemeData( primarySwatch: Colors.blue, ), home: MyHomePage(title: 'Flutter Demo Home Page'), );
