no setter
activeLayers ↔ List<Layer>: Get the list of layers from the current image editor changes.
getter/setter pair
activeScreenshot → ThreadCaptureState?: Retrieves the currently active screenshot based on the position.
no setter
activeScreenshotIsBroken → bool?: Check if the active screenshot is broken.
no setter

screenshots ↔ List<ThreadCaptureState>: List of captured screenshots for each state in the history.
getter/setter pair
stateHistory ↔ List<EditorStateHistory>: A getter that returns the list of historical editor states. This list provides a record of changes applied to the image, allowing for undo/redo functionality.

Methods

addHistory(EditorStateHistory history, {int historyLimit = 1000, bool enableScreenshotLimit = true}) → void: Adds a new entry to the history of image editor changes and updates the history pointer. This method ensures that any forward changes (redo history) are cleared before adding a new entry.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
redo() → void: Redoes the last undone change, moving the history pointer forward by one step. If there is no forward change available, this operation will throw an error due to out-of-bounds access handled by the historyPointer setter.
setHistoryLimit(int limit, bool enableScreenshotLimit) → void: Set the history limit to manage the maximum number of stored states.
toString() → String: A string representation of this object.
inherited
undo() → void: Undoes the last change by moving the history pointer back by one step. This reverts the editor to the previous state. If there is no previous state available, this operation will throw an error due to out-of-bounds access handled by the historyPointer setter.
updateActiveItems() → void: Updates the active items in the editor state based on the current history pointer.
updateLayerInteraction({required bool enableInteraction, required bool onlyCurrentHistory}) → void: Locks or unlocks all layers based on the provided parameters.

Operators

operator ==(Object other) → bool: The equality operator.
