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'
                }
            }
        }
    }
}

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

Remove Media Location permission

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.

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>
<key>NSMicrophoneUsageDescription</key>

Gallery

1. Use GalleryViewWrapper to make gallery view collapsible otherwise ignore it.

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

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

2. GalleryController can be used for extra setting and 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(
      gallerySetting: const GallerySetting(
        albumSubtitle: 'Collapsable',
        enableCamera: true,
        maximum: 10,
        requestType: RequestType.all,
      ),
      panelSetting: const PanelSetting(topMargin: 24.0),
    );
  }

  ...

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

  ...
}

3. Using GalleryViewField similarly as flutter TextField to pick media.

• onChanged – triggered every time user select/unselect media

• onSubmitted – triggered when user done with selection

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

4. You can also use GalleryView as a Widget.

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

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

• onCapture – triggered when photo/video capture completed

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