Parse error in method with default agrument

[mobilemindtech]

Hi,

Hi, I had an error while transpiling this code. So I removed the = {} and it compiled without error. Is this a bug?

Code with compilation error:

export class RootLayout extends GridLayout { // line 7
	open(view: View, options: RootLayoutOptions = {}): Promise<void>;
	close(view: View, exitTo?: TransitionAnimation): Promise<void>;
	topmost(): View;
	bringToFront(view: View, animated?: boolean): Promise<void>;
	closeAll(): Promise<void[]>;
	getShadeCover(): View;
	openShadeCover(options: ShadeCoverOptions = {}): Promise<void>;
	closeShadeCover(shadeCoverOptions: ShadeCoverOptions = {}): Promise<void>;
}
