ImageCropper class

The ImageCropper widget provides an interactive UI for users to crop and rotate images, supporting various predefined aspect ratios (e.g., 1:1, 4:3, 16:9) and custom options. Users can switch between landscape and portrait orientations for aspect ratios and apply the changes before saving.

  • The image parameter supplies the image to be cropped.
  • The availableRatios list defines preset aspect ratios for cropping.
  • The darkTheme parameter toggles between dark and light themes for the UI.
