Description:

Need Resume #
Need Resume is a package to implement onResume, onPause, onReady functionality on a Stateful widget (this is for every screen).
Quick Usage #
Replace State<MyWidget> with ResumableState<MyWidget> and then implement the void onResume(), void onPause(), and/or void onReady() abstract method. Replace Navigator.push() or Navigator.pushNamed() with push() or pushNamed()
Installation #
Add this to your package's pubspec.yaml file:
dependencies:
need_resume: ^1.0.7+1

Example #
Basic example:
import 'package:flutter/material.dart';
import 'package:need_resume/need_resume.dart';

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

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(title: 'My Application', home: HomeScreen());
}
}

class HomeScreen extends StatefulWidget {
@override
HomeScreenState createState() => HomeScreenState();
}

class HomeScreenState extends ResumableState<HomeScreen> {
@override
void onReady() {
// Implement your code inside here

print('HomeScreen is ready!');
}

@override
void onResume() {
// Implement your code inside here

print('HomeScreen is resumed!');
}

@override
void onPause() {
// Implement your code inside here

print('HomeScreen is paused!');
}

void goAnotherScreen() {
// Replace Navigator.push() or Navigator.pushNamed() with push() or pushNamed()

push(context, MaterialPageRoute(builder: (context) => AnotherScreen()));
}

@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: ElevatedButton(
child: Text('Go to Another Screen'),
onPressed: () {
goAnotherScreen();
},
),
),
);
}
}

class AnotherScreen extends StatefulWidget {
@override
AnotherScreenState createState() => AnotherScreenState();
}

class AnotherScreenState extends ResumableState<AnotherScreen> {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: ElevatedButton(
child: Text('Go Back'),
onPressed: () {
goBack();
},
),
),
);
}

void goBack() {
Navigator.pop(context);
}
}

How about to get data from a screen? Just use resume.data and resume.source:
import 'package:flutter/material.dart';
import 'package:need_resume/need_resume.dart';

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

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(title: 'My Application', home: HomeScreen());
}
}

class HomeScreen extends StatefulWidget {
@override
HomeScreenState createState() => HomeScreenState();
}

class HomeScreenState extends ResumableState<HomeScreen> {
@override
void onResume() {
switch (resume.source) {
case 'another_screen':
print('Data from AnotherScreen: ${resume.data}');
break;
}
}

void goAnotherScreen() {
push(context, MaterialPageRoute(builder: (context) => AnotherScreen()), 'another_screen');
}

@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: ElevatedButton(
child: Text('Go to Another Screen'),
onPressed: () {
goAnotherScreen();
},
),
),
);
}
}

class AnotherScreen extends StatefulWidget {
@override
AnotherScreenState createState() => AnotherScreenState();
}

class AnotherScreenState extends ResumableState<AnotherScreen> {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: ElevatedButton(
child: Text('Go Back'),
onPressed: () {
goBack();
},
),
),
);
}

void goBack() {
Navigator.pop(context, 'Hello!');
}
}
