getting code to run upon widget creation flutter - flutter

Question

I have a flutter camera app and am able to get a recorded video to play. The problem is, I am only able to get it to play when a button is pressed. How do I get the code to run when the widget(screen) is created instead of when the button is pressed so I don't have to press a button to get it to play? Here is my code:
Here is the code for when the button is pressed:
//raised button
RaisedButton(
onPressed: () {stopButtonPressed();},
//stopButtonPressed
void stopButtonPressed() {
print('stopButtonPressed hit');
stopVideoRecording().then((_) {
print('StopVideoRecording complete');
});
}
//stopVideoRecording
Future<void> stopVideoRecording() async {
print('stopVideoRecording hit');
await _startVideoPlayer();
}
//_startVideoPlayer
Future<void> _startVideoPlayer() async {
print('_startVideoPlayer hit');
print(Provider.of<SendDataModel>(context, listen: false).displayImageVideo());
final VideoPlayerController vcontroller =
VideoPlayerController.file(File(Provider.of<SendDataModel>(context, listen: false).displayImageVideo()));
videoPlayerListener = () {
if (videoController != null && videoController.value.size != null) {
if (mounted) setState(() {});
videoController.removeListener(videoPlayerListener);
}
};
vcontroller.addListener(videoPlayerListener);
await vcontroller.setLooping(true);
await vcontroller.initialize();
await videoController?.dispose();
if (mounted) {
setState(() {
//saveImagePath = null;
videoController = vcontroller;
});
}
await vcontroller.play();
} //startVideoPlayer
Thanks!

You can call the function from initState(). initState() is called only once when the StatefulWidget is inserted into the Widget tree, so it's a good place to initialize variables or do what you're trying to do.
class _MyHomePageState extends State<MyHomePage> {
#override
void initState() {
super.initState();
// Do anything you need done here
_startVideoPlayer();
// If you want a slight delay, use Future.delayed
Future.delayed(Duration(seconds: 1), (){
_startVideoPlayer();
});
}
#override
Widget build(BuildContext context) {
return Scaffold(
// rest of app
