return route is! DialogRoute;
});
1- Generate and get .jks from android studio.
2- Create a key.properties under android file as following format.
storePassword=
keyPassword=
keyAlias=
storeFile= //file path of jks3- Go to your app level build gradle and get key.properties with following code.
def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}4- Add signing configurations inside the android tag.
signingConfigs {
release {
keyAlias keystoreProperties['keyAlias']
keyPassword keystoreProperties['keyPassword']
storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
storePassword keystoreProperties['storePassword']
}
}5- Make sure about your signingConfig is release as following ;
buildTypes {
release {
signingConfig signingConfigs.release
}
}6- Run ‘flutter build appbundle’ command .
class _MyHomePageState extends State<MyHomePage> with WidgetsBindingObserver {
@override
void initState() {
super.initState();
WidgetsBinding.instance!.addObserver(this);
}
// ...
@override
void dispose() {
WidgetsBinding.instance!.removeObserver(this);
super.dispose();
}
@override
void didChangeAppLifecycleState(AppLifecycleState state) {
super.didChangeAppLifecycleState(state);
print('AppLifecycleState: $state');
if (state == AppLifecycleState.resumed) {
// User has returned to the app (app is in the foreground and active)
print('myState: User returned to the app!');
// Perform actions here, e.g., refresh data, show a message, etc.
} else if (state == AppLifecycleState.paused) {
// App is in the background
print('myState: App went to background');
} else if (state == AppLifecycleState.inactive) {
// App is inactive (e.g., a phone call came in, or app is about to go to background)
print('myState: App is inactive');
}
}
進入debug模式進行調試發現錯誤
======== Exception caught by widgets library =======================================================
The following assertion was thrown while applying parent data.:
Incorrect use of ParentDataWidget.
The ParentDataWidget Expanded(flex: 1) wants to apply ParentData of type FlexParentData to a RenderObject, which has been set up to accept ParentData of incompatible type StackParentData.
Usually, this means that the Expanded widget has the wrong ancestor RenderObjectWidget. Typically, Expanded widgets are placed directly inside Flex widgets.
The offending Expanded is currently placed inside a Stack widget.
