+# file\_selector\_android
+
+The Android implementation of [`file_selector`][1].
+
+## Usage
+
+This package is [endorsed][2], which means you can simply use `file_selector`
+normally. This package will be automatically included in your app when you do,
+so you do not need to add it to your `pubspec.yaml`.
+
+However, if you `import` this package to use any of its APIs directly, you
+should add it to your `pubspec.yaml` as usual.
