将此设置用于图像小部件：图像。内存（字节）。您可以find more documentation on the Flutter dev website。

由于评分最高的答案使用flutter/widget.dart，因此仅使用dart:ui

Future<Image> tinypng() async {
  final bytes = Uint8List.fromList([
    137, 80, 78, 71, 13, 10, 26, 10, 0, 0, 0, 13, 73, 72, 68, 82, 0, 0, 0,
    1, 0, 0, 0, 1, 8, 6, 0, 0, 0, 31, 21, 196, 137, 0, 0, 0, 10, 73, 68, 65,
    84, 120, 156, 99, 0, 1, 0, 0, 5, 0, 1, 13, 10, 45, 180, 0, 0, 0, 0, 73,
    69, 78, 68, 174, 66, 96, 130 // prevent dartfmt
  ]);

  // copy from decodeImageFromList of package:flutter/painting.dart
  final codec = await instantiateImageCodec(bytes);
  final frameInfo = await codec.getNextFrame();
  return frameInfo.image;
}

这将返回小部件

Image.memory(Uint8List);
