Install

1. Add dependency

Add this to your package's pubspec.yaml file:

  gallery_asset_picker: ^latest_version

2. Import it

Now in your Dart code, you can use:

import 'package:gallery_asset_picker/gallery_asset_picker.dart';

Setup

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

1. Android

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

minSdkVersion 21

• Required permissions: READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE, ACCESS_MEDIA_LOCATION.

• Glide

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'
                }
            }
        }
    }
}

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

2. iOS

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>

Usage

• Use GalleryAssetPicker.initialize to config for the gallery

GalleryAssetPicker.initialize(GalleryConfig(
    enableCamera: true,
    crossAxisCount: 3,
    colorScheme: const ColorScheme.light(primary: Colors.blue),
    onReachMaximum: () {
      Fluttertoast.showToast(
        msg: "You have reached the allowed number of images",
        toastLength: Toast.LENGTH_SHORT,
        gravity: ToastGravity.CENTER,
        textColor: Colors.white,
        fontSize: 16.0,
      );
    },
    textTheme: const TextTheme(
      bodyMedium: TextStyle(fontSize: 16),
      titleMedium: TextStyle(fontSize: 14, fontWeight: FontWeight.w700),
      titleSmall: TextStyle(fontSize: 14, fontWeight: FontWeight.w500),
    ),
));

• To make the gallery view sliding, use the SlidableGalleryOverlay; otherwise, ignore it

class SlidableGalleryDemo extends StatelessWidget {
 late final GalleryController galleryController;

 ...

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

• Using GalleryAssetPicker.pick() to pick assets

  ...
  onPressed : () async {
    final _selectedAssets = await GalleryAssetPicker.pick(
      context,
      maxCount: 5,
      requestType: RequestType.image,
    );
  }
  ...

• You can use other widgets included in the package, and for a more thorough implementation and modification, browse the example app
