Target of URL doesn't exist

[luke1128qq]

I want to import 「image_editor 1.3.0」 into my FlutterFlow project.
However, after importing it, I keep encountering the error message:

"Target of URI doesn't exist: 'package:flutter_image_editor_example/home_page.dart'. Try creating the file referenced by the URI, or try using a URI for a file that does exist."

Even when I add the dependency "flutter_image_editor: ^2.1.0," the problem remains unsolved.

this is my code , help me plz

// Automatic FlutterFlow imports
import '/flutter_flow/flutter_flow_theme.dart';
import '/flutter_flow/flutter_flow_util.dart';
import '/custom_code/widgets/index.dart'; // Imports other custom widgets
import '/flutter_flow/custom_functions.dart'; // Imports custom functions
import 'package:flutter/material.dart';
// Begin custom widget code
// DO NOT REMOVE OR MODIFY THE CODE ABOVE!

import 'dart:typed_data';
import 'package:flutter/services.dart';
import 'package:flutter_image_editor_example/home_page.dart';
import 'package:oktoast/oktoast.dart';

class ImgEditor extends StatefulWidget {
const ImgEditor({
Key? key,
this.width,
this.height,
}) : super(key: key);

final double? width;
final double? height;

@OverRide
_ImgEditorState createState() => _ImgEditorState();
}

class _ImgEditorState extends State {
@OverRide
Widget build(BuildContext context) {
return OKToast(
position: ToastPosition.bottom,
child: MaterialApp(
home: IndexPage(),
),
);
}
}

Future loadFromAsset(String key) async {
final ByteData byteData = await rootBundle.load(key);
return byteData.buffer.asUint8List();
}
