import 'package:drishya_picker/drishya_picker.dart';

For more details (if needed) you can go through Photo Manager and Camera readme section as well.

Change the minimum Android sdk version to 21 (or higher) in your android/app/build.gradle file.

minSdkVersion 21

Required permissions: INTERNET, READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE, ACCESS_MEDIA_LOCATION. If you don't need the ACCESS_MEDIA_LOCATION permission, see Disable ACCESS_MEDIA_LOCATION permission.

Android native use glide to create image thumb bytes, version is 4.11.0.

If your other android library use the library, and version is not same, then you need edit your android project's build.gradle.

rootProject.allprojects {

    subprojects {
        project.configurations.all {
            resolutionStrategy.eachDependency { details ->
                if (details.requested.group == 'com.github.bumptech.glide'
                        && details.requested.name.contains('glide')) {
                    details.useVersion '4.11.0'
                }
            }
        }
    }
}

And, if you want to use ProGuard, you can see the ProGuard of Glide.

Android contains ACCESS_MEDIA_LOCATION permission by default.

This permission is introduced in Android Q. If your app doesn't need this permission, you need to add the following node to the Android manifest in your app.

<uses-permission
  android:name="android.permission.ACCESS_MEDIA_LOCATION"
  tools:node="remove"
  />

If you found some warning logs with Glide appearing, then the main project needs an implementation of AppGlideModule. See Generated API.

Add following content to info.plist.

<key>NSPhotoLibraryUsageDescription</key>
<string>Replace with your permission description..</string>
<key>NSCameraUsageDescription</key>
<string>Replace with your permission description..</string>
<key>NSMicrophoneUsageDescription</key>

1. Use SlidableGallery to make gallery view slidable otherwise ignore it.

class PickerDemo extends StatelessWidget {
 late final GalleryController controller;
 
 ...

 @override
 Widget build(BuildContext context) {
   return SlidableGallery(
     controller: controller,
     child: Scaffold(
       body: ...
     ),
   );
 }
}

2. GallerySetting can be used for extra setting while picking media.

• Using pick() function on controller to pick media.

class PickerDemo extends StatelessWidget {
  late final GalleryController controller;

  @override
  void initState() {
    super.initState();
    controller = GalleryController();
  }

    
  final _gallerySetting = GallerySetting(
      enableCamera: true,
      maximumCount: 10,
      requestType: RequestType.all,
      editorSetting: EditorSetting(colors: _colors, stickers: _stickers1),
      cameraSetting: const CameraSetting(videoDuration: Duration(seconds: 15)),
      cameraTextEditorSetting: EditorSetting(
        backgrounds: _defaultBackgrounds,
        colors: _colors.take(4).toList(),
        stickers: _stickers2,
      ),
      cameraPhotoEditorSetting: EditorSetting(
        colors: _colors.skip(4).toList(),
        stickers: _stickers3,
      ),
    );

  ...

  onPressed : () async {
    final entities = await controller.pick(context,setting:setting);
  }

  ...
}

3. Using GalleryViewField similarly as flutter TextField to pick media. (Recommended approach, as creating and disposing of the controller has been already cared-of )

• onChanged – triggered every time user select/unselect media

• onSubmitted – triggered when user done with selection

GalleryViewField(
  selectedEntities: [],
  onChanged: (entity, removed) {
     ...
  },
  onSubmitted: (list) {
     ...
  }
  child: const Icon(Icons.camera),
),

4. You can also use GalleryView as a Widget.

5. Browse the example app for more in-depth implementation and customization.

1. Using pick() function on CameraView to pick media.

  ...
  onPressed : () async {
    final entity = await CameraView.pick();
  }
  ...

2. Using CameraViewField similarly as flutter TextField to pick media.

• onCapture – triggered when photo/video capture completed

GalleryViewField(
  onCapture: (entity) {
     ...
  },
  child: const Icon(Icons.camera),
),

3. You can also use CameraView as a Widget.
