Flutter:如何获取图像像素的颜色？

import 'dart:typed_data';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();

  // 加载图像
  final ByteData imageData = await rootBundle.load('assets/images/image.png');

  // 将图像数据转换为 Uint8List
  Uint8List imageBytes = imageData.buffer.asUint8List();

  // 创建图片对象
  final image = Image.memory(imageBytes);

  // 绘制图片
  final completer = Completer<void>();
  image.image.resolve(ImageConfiguration()).addListener(
    ImageStreamListener((ImageInfo info, bool synchronousCall) {
      // 获取图片的像素数据
      final byteData = info.image.toByteData();
      final Uint32List pixels = byteData.buffer.asUint32List();

      // 获取第一个像素的颜色值
      final color = Color(pixels[0]);

      // 打印颜色值
      print('第一个像素的颜色值：$color');

      completer.complete();
    }),
  );

  await completer.future;
  print('获取图像像素颜色完成');
}
