ResizablePaneController mixin

Mixin for controllers that manage resizable pane sizing.

Provides methods to resize, collapse, and expand panels programmatically. Implementations include AbsoluteResizablePaneController for fixed sizes and FlexibleResizablePaneController for flexible/proportional sizes.

addListener(VoidCallback listener) → void: Register a closure to be called when the object notifies its listeners.
inherited
collapse() → void: Collapses the panel to its minimum size.
computeSize(double paneSize, {double? minSize, double? maxSize}) → double: Computes the actual size based on paneSize and optional constraints.
expand() → void: Expands the panel to its maximum or default size.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that the object notifies.
inherited
resize(double newSize, double paneSize) → void: Resizes the controller to the given newSize within the paneSize bounds.
toString() → String: A string representation of this object.
inherited
tryCollapse([PanelSibling direction = PanelSibling.both]) → bool: Attempts to collapse the panel in the specified direction.
tryExpand([PanelSibling direction = PanelSibling.both]) → bool: Attempts to expand the panel in the specified direction.
tryExpandSize(double size, [PanelSibling direction = PanelSibling.both]) → bool: Attempts to expand by size pixels in the specified direction.
