如何在图片上添加文字并保存在flutter中？

dependencies:
  flutter_image: ^1.0.0
  flutter_image_editor: ^1.0.0

import 'package:flutter/material.dart';
import 'package:flutter_image_editor/flutter_image_editor.dart';
import 'package:flutter_image_editor/enum.dart';

final editor = ImageEditor();

final image = await editor.loadImageFromAsset('assets/images/image.jpg');
final width = image.width;
final height = image.height;

final textLayer = TextLayer(
  text: 'Hello, Flutter!',
  font: 'Arial',
  fontSize: 24,
  color: Colors.white,
  position: Offset(50, 50), // 文字在图片上的位置
);

editor.addLayer(textLayer);

final editedImage = await editor.execute(width, height);

await editedImage.saveTo('path/to/save/image.jpg');
