Code:

File imageFile = File("content://media/external/images/media/138501");

DecorationImage(image: ExactAssetImage(imageFile.path),fit: BoxFit.fill)

You can use uri_to_file package. It supports content:// URI.

Simple to use (Updated)

import 'package:uri_to_file/uri_to_file.dart';

try {
  String uriString = 'content://sample.txt';

  // Don't pass uri parameter using [Uri] object via uri.toString().
  // Because uri.toString() changes the string to lowercase which causes this package to misbehave

  // If you are using uni_links package for deep linking purpose.
  // Pass the uri string using getInitialLink() or linkStream

  File file = await toFile(uriString);
} on UnsupportedError catch (e) {
  print(e.message);
} on IOException catch (e) {
  print(e);
} catch (e) {
  print(e);
}

then you can use this file as you want

Important note

Don't pass uri value like this

File file = await toFile(uri.toString());

Use like this if you are using uni_links package for deep linking purpose. Use getInitialLink() or linkStream

String? uriString = await getInitialLink();
if (uriString != null) {
  File file = await toFile(uriString);
}

linkStream.listen((uriString) async {
  if (uriString != null) {
    File file = await toFile(uriString!);
  }
});

This will not modify the uri string as we are not using uri.toString()

So this package will work fine
