Is there an existing issue for this?

Steps to reproduce

  1. Run the code sample
  2. The output doesn't match the expected output

Expected results

It prints [254, 253, 252, 128]

Actual results

It prints [253, 251, 251, 128]

Code sample

Code sample 
import 'dart:ui';

import 'package:flutter/widgets.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  @override
  void initState() {
    super.initState();
    _execute();
  }

  void _execute() async {
    final program = await FragmentProgram.fromAsset('assets/shader.frag');
    final pictureRecorder = PictureRecorder();
    final canvas = Canvas(pictureRecorder);
    canvas.drawRect(
      Offset.zero & const Size(1, 1),
      Paint()..shader = program.fragmentShader(),
    );
    final picture = pictureRecorder.endRecording();
    final image = await picture.toImage(1, 1);
    final bytesStraight =
        await image.toByteData(format: ImageByteFormat.rawStraightRgba);
    print(bytesStraight!.buffer.asUint8List());
  }

  @override
  Widget build(BuildContext context) {
    return const SizedBox.shrink();
  }
}
layout(location=0)out vec4 fragColor;

void main() {
  float alpha = 0.5;
  // Premultiply alpha
  fragColor = vec4(254/255.0 * alpha, 253/255.0 * alpha, 252/255.0 * alpha, alpha);
}
