推荐答案

即使您仅在 pubspec.yaml中指定资产文件夹，则flutter编译器会在 AssetManifest.json 文件中列出这些文件夹中的所有文件。我们要做的就是读取此文件：

Even if you specified only asset folders in pubspec.yaml, the flutter compiler lists all files from these folders in AssetManifest.json file. All we have to do is read this file:

final manifestJson = await DefaultAssetBundle.of(context).loadString('AssetManifest.json');
final images = json.decode(manifestJson).keys.where((String key) => key.startsWith('assets/images'));
