Changing a MaterialApp's initialRoute does not rebuild the widget. #12454
Description
Steps to Reproduce
Run this demo app:
The key code is:
class _MyAppState extends State<MyApp> {
String nextRoute = homeRoute;
void _nextRoute() {
String route = secondRoute;
if (nextRoute == secondRoute) route = homeRoute;
setState(() {
print('setting route to $route');
nextRoute = route;
});
}
@override
Widget build(BuildContext context) {
final routes = {
homeRoute: (BuildContext context) => new MyHomePage(nextRoute: _nextRoute),
secondRoute: (BuildContext context) => new _MySecondRoute(_nextRoute),
};
return new MaterialApp(
title: 'Flutter Demo',
theme: new ThemeData(
primarySwatch: Colors.blue,
),
routes: routes,
initialRoute: nextRoute,
);
}
}Triggering the _nextRoute() function prints the new initialRoute, but the application is not rebuilt with the new route.
