you can also use GlobalKey to access ProgressHudState

class HomePage extends StatefulWidget {
@override
_HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
GlobalKey<ProgressHudState> _globalKey = GlobalKey();

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("hud demo"),
),
body: ProgressHud(
key: _globalKey,
maximumDismissDuration: Duration(seconds: 2),
child: Center(
child: Builder(builder: (context) {
return Column(
mainAxisSize: MainAxisSize.min,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
RaisedButton(
onPressed: () {
_showLoadingHud(context);
},
child: Text("show loading"),
),
],
);
}),
),
),
);
}

_showLoadingHud(BuildContext context) async {
_globalKey.currentState?.show(ProgressHudType.loading, "loading...");
await Future.delayed(const Duration(seconds: 1));
_globalKey.currentState?.dismiss();
}

other ProgressHudType
// show successHud with text
_showSuccessHud(BuildContext context) {
ProgressHud.of(context)?.showAndDismiss(ProgressHudType.success, "load success");
}

// show errorHud with text
_showErrorHud(BuildContext context) {
ProgressHud.of(context)?.showAndDismiss(ProgressHudType.error, "load fail");
}

// show progressHud with progress and text
_showProgressHud(BuildContext context) {
var hud = ProgressHud.of(context);
hud?.show(ProgressHudType.progress, "loading");

double current = 0;
Timer.periodic(Duration(milliseconds: 1000.0 ~/ 60), (timer) {
current += 1;
var progress = current / 100;
hud?.updateProgress(progress, "loading $current%");
if (progress == 1) {
// finished
hud?.showAndDismiss(ProgressHudType.success, "load success");
timer.cancel();
}
});

global HUD #

mark global hud with isGlobalHud, there must be only one global hud, it always define before MeterialApp

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return ProgressHud(
// mark hud as global, it should be only one global hud
isGlobalHud: true,
child: MaterialApp(
home: HomePage()
),
);
}
}

use global hud with static method, similar to hud instance

void example() {
ProgressHud.showLoading();
ProgressHud.dismiss();

ProgressHud.showAndDismiss(ProgressHudType.success, "load success");
ProgressHud.showAndDismiss(ProgressHudType.error, "load fail");

ProgressHud.show(ProgressHudType.progress, "loading");
ProgressHud.updateProgress(progress, "loading 20%");

ProgressHud.showAndDismiss(ProgressHudType.success, "load success");
}
