Capture a processed photo in Flutter

Prerequisites

• A working Flutter quickstart
• An initialized NosmaiCameraPreview

Capture the processed frame

final nosmai = NosmaiFlutter.instance;
final photo = await nosmai.capturePhoto();

if (!photo.success || photo.imageData == null) {
  throw StateError(photo.error ?? 'Photo capture failed');
}

final bytes = photo.imageData!;

imageData contains the captured image with the active Nosmai effects.

Save it to the gallery

final saved = await nosmai.saveImageToGallery(
  bytes,
  name: 'nosmai-photo',
);

Saving is optional. Request the platform photo-library permission when the host application requires it.

Verify it worked

Apply a visible filter, capture once, and confirm photo.success is true, the byte list is not empty, and the saved image contains the same effect.
