 ## use
 
 ```dart
-void _pickImage() async {
+void pickAsset() async {
     List<AssetEntity> imgList = await PhotoPicker.pickAsset(
       context: context,
       // BuildContext requied
       loadingDelegate:
           this, // if you want to build custom loading widget,extends LoadingDelegate [see example/lib/main.dart]
 
+      badgeDelegate: const DefaultBadgeDelegate(), /// or custom class extends [BadgeDelegate]
+
       pickType: type, // all/image/video
+
+      List<AssetPathEntity> photoList, /// when [photoList] is not null , [pickType] invalid .
     );
 ```
 
+## about photoList
+
+You can use [photo_manager] package to get `List<AssetPathEntity>` and handle or cache.
+
+This parameter is then passed into the `pickAsset` method, where the incoming photoList is rendered instead of the data in the album.
+
 ## whole example
 
 you can see [github](https://github.com/caijinglong/flutter_photo/blob/master/example/) [main.dart](https://github.com/caijinglong/flutter_photo/blob/master/example/lib/main.dart)
