[AnnatarHe]

related #23621 and seems like not fixed yet.

Steps to Reproduce

canvas can not draw image in release mode.

1. copy code to main.dart

import 'package:flutter/material.dart';
import 'dart:typed_data';
import 'dart:ui' as ui;
import 'package:http/http.dart' as http;

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);
  final String title;

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  ByteData byteData;

  @override
  void initState() {
    super.initState();

    this._renderImage();
  }

  Future<ui.Image> _loadImage(String url) async {
    final _image = await http.readBytes(url);

    final bg = await ui.instantiateImageCodec(_image);
    final frame = await bg.getNextFrame();
    final img = frame.image;
    return img;
  }

  _renderImage() async {
    final recorder = new ui.PictureRecorder();
    final canvas = new Canvas(
        recorder,
        Rect.fromPoints(
            Offset(0.0, 0.0),
            Offset(200, 200)
        )
    );
    final img = await this._loadImage('https://ws1.sinaimg.cn/large/8112eefdgy1g08jm47mh2j20u01hc4dq.jpg');
    canvas.drawImage(img, Offset.zero, Paint());
    final picture = recorder.endRecording();
    final png = await picture.toImage(200, 200).toByteData(format: ui.ImageByteFormat.png);

    setState(() {
      byteData = png;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: byteData == null ? Placeholder() : Image.memory(this.byteData.buffer.asUint8List())
      )
    );
  }
}

2. open app

run flutter by command flutter run --enable-software-rendering and flutter run --release

the image has shown in software rendering and empty in release mode
