}

/// 单选
SingleAssetPicker();

/// 多选
MultipleAssetPicker();

直接调用方法选择


void fun() {
  /// 选择Actions
  FlAssetsPicker.showPickActions();

  /// 最原始的资源选择器
  FlAssetsPicker.showPickAssets();
  FlAssetsPicker.showPickAssetsWithDelegate();

  /// 从相机拍摄
  FlAssetsPicker.showPickFromCamera();

  /// 依次选择Actions和资源选择器
  FlAssetsPicker.showPickWithOptionalActions();
