switchCamera method

Future<void> switchCamera([ SwitchCameraOption option = const ToggleDirection() ])

Switch the camera based on the given option.

The option parameter determines how the camera is switched:

• ToggleDirection: Toggles between front and back cameras (default).
• ToggleLensType: Cycles through available lens types on the current camera facing direction.
• SelectCamera: Selects a specific camera direction and/or lens type.

For ToggleDirection, does nothing if the device has less than 2 cameras, or if the current camera direction is CameraFacing.unknown or CameraFacing.external.

For ToggleLensType, does nothing if the device has less than 2 lens types available.

Implementation

Future<void> switchCamera([
  SwitchCameraOption option = const ToggleDirection(),
]) async {
  _throwIfNotInitialized();

  switch (option) {
    case ToggleDirection():
      await _toggleCameraDirection();
    case ToggleLensType():
      await _toggleLensType();
    case SelectCamera(:final facingDirection, :final lensType):
      await _selectCamera(
        facingDirection: facingDirection,
        lensType: lensType,
      );
  }
}
