1. request permission

You must get the user's permission on android/ios.

var result = await PhotoManager.requestPermission();
if (result) {
    // success
} else {
    // fail
    // if result is fail, you can call PhotoManger.openSetting();  to open android/ios applicaton's setting to get permission
}

2. you get all of asset list (gallery)

List<AssetPathEntity> list = await PhotoManager.getAssetPathList();

3. get asset list from imagePath

List<AssetEntity> imageList = await data.assetList;

4. use the AssetEntity

AssetEntity entity = imageList[0];

File file = await entity.file; // image file

List<int> fileData = await entity.fullData; // image/video file bytes

Uint8List thumbBytes = await entity.thumbData; // thumb data ,you can use Image.memory(thumbBytes); size is 64px*64px;

Uint8List thumbDataWithSize = await entity.thumbDataWithSize(width,height); //Just like thumbnails, you can specify your own size. unit is px;

AssetType type = entity.type; // the type of asset enum of other,image,video
