FileManager is a wonderful widget that allows you to manage files and folders, pick files and folders, and do a lot more.

Designed to feel like part of the Flutter framework.

##  Compatibility

✅ &nbsp; Android </br>
✅ &nbsp; Windows </br>
✅ &nbsp; Linux </br>
❌ &nbsp; iOS (active issue: [iOS support](https://github.com/DevsOnFlutter/file_manager/issues/7))

## Usage

Make sure to check out [examples](https://github.com/DevsOnFlutter/file_manager/blob/main/example/lib/main.dart) for more details.

### Installation

Give storage permission to application

Beside needing to add **WRITE_EXTERNAL_STORAGE** and **READ_EXTERNAL_STORAGE** to your android/app/src/main/AndroidManifest.xml.

```xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.xxx.yyy">
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

    <application
      android:requestLegacyExternalStorage="true"   
      ...
...
</manifest>
```

also add for Android 10

```
    <application
      android:requestLegacyExternalStorage="true"   
      ...
```

**You also need Runtime Request Permission**
allow storage permission from app setting manually or you may use any package such as [`permission_handler`](https://pub.dev/packages/permission_handler).

Add the following line to `pubspec.yaml`:

```yaml
dependencies:
  file_manager: ^1.0.0
```

### Basic setup

*The complete example is available [here](https://github.com/DevsOnFlutter/file_manager/blob/main/example/lib/main.dart).*

Required parameter for **FileManager** are `controller` and `builder`
* `controller` The controller updates value and notifies its listeners, and FileManager updates itself appropriately whenever the user modifies the path or changes the sort-type with an associated FileManagerController.
```
final FileManagerController controller = FileManagerController();
```
* `builder` This function allows you to create custom widgets and retrieve a list of entities `List<FileSystemEntity>.`



Sample code
```dart
FileManager(
    controller: controller,
    builder: (context, snapshot) {

    final List<FileSystemEntity> entities = snapshot;

      return ListView.builder(

        itemCount: entities.length,

        itemBuilder: (context, index) {
          return Card(
            child: ListTile(

              leading: isFile(entities[index])

                  ? Icon(Icons.feed_outlined)
                  : Icon(Icons.folder),

              title: Text(basename(entities[index])),

              onTap: () {

                if (isDirectory(entities[index])) {
                    controller.openDirectory(entities[index]);   // open directory

                  } else {
                      // Perform file-related tasks.
                  }
              },
            ),
          );
        },
      );
  },
),
```

## Contributions

Contributions are welcomed!

If you feel that a hook is missing, feel free to open a pull-request.

For a custom-hook to be merged, you will need to do the following:

- Describe the use-case.

-  Open an issue explaining why we need this hook, how to use it, ...
  This is important as a hook will not get merged if the hook doens't appeal to
  a large number of people.

-  If your hook is rejected, don't worry! A rejection doesn't mean that it won't
  be merged later in the future if more people shows an interest in it.
  In the mean-time, feel free to publish your hook as a package on https://pub.dev.

-  A hook will not be merged unles fully tested, to avoid breaking it inadvertendly

  in the future.
