如何在没有BuildContext的情况下解析ImageProvider

import 'package:flutter/widgets.dart';
import 'package:flutter/services.dart' show rootBundle;
import 'dart:async';
import 'dart:typed_data';
import 'dart:ui' as ui;

Future<ui.Image> loadUiImage(String assetPath) async {
  ByteData data = await rootBundle.load(assetPath);
  ui.Codec codec = await ui.instantiateImageCodec(data.buffer.asUint8List());
  ui.FrameInfo fi = await codec.getNextFrame();
  return fi.image;
}

String imagePath = "assets/images/example.png"; // 替换为实际的图片路径
ui.Image image = await loadUiImage(imagePath);
