Does anyone know why this happens?
I did all the steps right but still it crashes after it loads.

WidgetsBinding.instance?.addPostFrameCallback((_) {
Navigator.pushReplacement(
context,
MaterialPageRoute(
builder: (context) {
return LocationScreen(locationWeather: weatherData);
},
),
);
});

Try this, It works for me.
