this is my splash screen and I provide the future method to navigate automatically to another screen,
class SplashScreen extends StatelessWidget {
#override
Widget build(BuildContext context) {
Provider.of<DataBaseProvider>(context).getAllEmployees();
Future.delayed(Duration(seconds: 2)).then((value) {
Navigator.of(context).pushReplacement(MaterialPageRoute(builder: (context) => ListViewEmployees()));
});
return Scaffold(
body: Container(
child: Center(
child: GestureDetector(
onTap: (){
Navigator.of(context).pushReplacement(MaterialPageRoute(builder: (context) => ListViewEmployees()));
},
child: Text(
'Hello!' ,
style: TextStyle(
color: Colors.deepPurple ,
fontSize: 18 ,
),
),
),
),
),
);
}
}
and this is the error message

when I delete future delayed, and make the navigate by a button click, the error disappear
SOLVED !!!!!! here
Test breaks when using Future.delayed
The reason for this error is that you're trying to Navigate to a page while the current screen is still being rendered. Future.delayed() can be potentially used as it provides a delay while the current screen is being built. What happens when the screen being built is still not finished and Future.delayed() is that the workaround causes issues.
Another workaround is setting a fixed Timer
Timer(const Duration(seconds: 4), () {
// Navigate to next screen
});
It's still best to avoid automatically navigating to a next screen if possible.

When I try to run my app in an emulator in Android Studio I get the following error. I have to say that it worked before and stopped working after some updates of SDK to v.29. Is there something I have to change now?
I tried to kill and restart adb server and disabling heap protection so far..

And here's a picture of the SDK tools. Maybe it's important...
It appears to be an update problem with Platform-Tools version 28, more specific with the ADB tool. There is a temporary fix so you can follow the steps provided in this link https://github.com/flutter/flutter/issues/33938#issuecomment-499250288
PD. If you already installed API 29 version probably you need to downgrade. v.29 --> v.28

Here is the code i am using:
_readCarachteristics(services) async {
for (BluetoothService service in services){
_characteristics = service.characteristics;
for (BluetoothCharacteristic characteristic in _characteristics) {
final List<int> value = await _device.readCharacteristic(characteristic);
}
}
_services = await device.discoverServices();
_readCarachteristics(_services);
I read this issue: https://github.com/pauldemarco/flutter_blue/issues/57 but could'nt manage to solve it. Thanks for your support.
UPDATED
It seems that there are specific characteristics sent by the beacon that are composed in a special way that is breaking the readCharacteristic method. They are supposed to contain two subtypes of uuid that are not been read by the readDescriptor function.
There are three services out of which the third one should be used to read and write characteristic.The first two are generic and the third one is custom service using which it will work. Try this :
_scanResult.device.discoverServices().then((services){
services[2].characteristics[0].read();
});
Dear stackoverflow team,
I recently compiled paraview from source on ubuntu using the following build instructions, however I get core dumped when opening any *vtk,*exodus file.

After installing it, and removing the "libqgtk3.so" file, paraview was able to launch, but the problem comes when trying to read any vtk or exodus file, for which I immediately get the following errors: I don't know at this point what to do. My guess is I missed some other command that requires other package to be installed?. Please any help will be gratefully appreciated.

i am attaching so remotely via thrift, after attach a1.so a2.so then detach a1.so a2.so , when detach more a1.so which does not exist, it core dump as this, but when we attach a1.so detach a1.so detach a1.so , it works well
any clue for this issue or how could i debug since i have add try-catch to this serv func, but no exception throw out, thanks
