Methods

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

public void Dispose()

Dispose(bool)

Disposes the resources used by the NaluShell.

protected virtual void Dispose(bool disposing)

Parameters

disposing bool

True when disposing managed resources.

OnBackButtonPressed()

Determines the behavior when the back button of the page is pressed.

protected override bool OnBackButtonPressed()

Returns

bool

true when the back navigation was handled by the override, otherwise false.

Remarks

Application developers can override this method to provide behavior when the back button is pressed. When overridden to handle or cancel the navigation yourself, this method should return true.

This only works on Android and UWP for the hardware back button. On iOS, this method will never be called because there is no hardware back button.
