[The argument type 'Uint8List' can't be assigned to the parameter type 'File'.dartargument_type_not_assignable Uint8List? bytes Type: Uint8List?]
Reference image - (https://i.stack.imgur.com/iSbTP.png)
My Code:
IconButton(
onPressed: () async {
Uint8List? bytes = await screenshotController.capture();
imageProvider.changeImage(bytes!);
if (!mounted) return;
Navigator.of(context).pop();
},
icon: const Icon(Icons.done),
)
Can someone suggest how to solve this error please? I am a beginner
I tried to pass bytes as parameter with null check, but this isn't working

Summary
The error is related to assigning a Uint8List to a parameter that expects a File. The problem seems to be with the capture() method.
One possible solution is to convert the Uint8List to a File object before passing it as a parameter. You can do this by using the path_provider package to get the temporary directory and then creating a new File using the Uint8List and the temporary directory.
Here's an example of how you can solve the error:
```dart
import 'package:path_provider/path_provider.dart';
...
IconButton(
onPressed: () async {
Uint8List? bytes = await screenshotController.capture();
