问如何在Flutter中通过url从网络图像中获取Uint8List？

EN

Uint8List yourVar;
final DecoderCallback callback = (Uint8List bytes, {int cacheWidth, int cacheHeight}) {
        yourVar = bytes.buffer.asUint8List();
        return instantiateImageCodec(bytes, targetWidth: cacheWidth, targetHeight: cacheHeight);
      };
ImageProvider provider = NetworkImage(yourImageUrl);
    provider.obtainKey(createLocalImageConfiguration(context)).then((key) {
      provider.load(key, callback);
    });

Uint8List bytes = (await NetworkAssetBundle(Uri.parse(url)).load(url))
    .buffer
    .asUint8List();

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

//Get the image from the URL and then convert it to Uint8List
Uint8List bytes = (await NetworkAssetBundle(Uri.parse('https://some_image_url.png'))
            .load('https://some_image_url.png'))
            .buffer
            .asUint8List();
