Progress Dialog With Value Update

Setup for Progress Value Update

Add this to your MyApp build function

import 'package:provider/provider.dart';

MultiProvider(  
	providers: [  
		ChangeNotifierProvider(create: (context) => ProgressModel()),  
	]
	child: MaterialApp( ... ),
);

Like this

// MyApp class build function return like this
class MyApp extends StatelessWidget {  
	@override  
	Widget build(BuildContext context) {  
		return MultiProvider(  
			providers: [  
				ChangeNotifierProvider(create: (context) => ProgressModel()),  
			],  
			child: MaterialApp(  
				debugShowCheckedModeBanner: false,  
				title: 'Fialogs Demo',  
				theme: lightTheme(),    
				home: MyHomePage(title: 'Fialogs Demo Home Page'),  
			),  
		);  
	}
}

Update Progress Value

Update progress model value from where you call the progress dialog function

updateProgress() async {  
	var model = context.read<ProgressModel>();  
	model.setValue(0.0);  
	for(var i = 0.00; i <= 1.00; i = i + 0.01) {  
		await Future.delayed(Duration(milliseconds: 100), () {  
			var model = context.read<ProgressModel>();  
			if (i > 0.99) {  
				model.setValue(1.0);  
			} else {  
				model.setValue(i);  
			}  
		});  
	}  
}

Progress Dialog Function should called from ChangeNotifierProvider

Scaffold(  
	appBar: AppBar(  
		title: Text(widget.title),  
	),  
	body: ChangeNotifierProvider(  
		create: (context) => ProgressModel(),
		child: Column(
			children: <Widget>[ ... ],
		),
	),
);
