AssetPickerViewerProvider<A> constructor

AssetPickerViewerProvider<A>(List<A>? assets, { int maxAssets = defaultMaxAssetsCount, })

Copy selected assets for editing when constructing. 构造时深拷贝已选择的资源集合，用于后续编辑。

Implementation

AssetPickerViewerProvider(
  List<A>? assets, {
  this.maxAssets = defaultMaxAssetsCount,
}) : assert(maxAssets > 0, 'maxAssets must be greater than 0.') {
  _currentlySelectedAssets = (assets ?? <A>[]).toList();
}
