Possible bug in example code

[pedro-w]

In this snippet

react-native-windows-samples/docs/windowsbrush-and-theme.md

Lines 53 to 59 in fd83101

	componentDidMount() {
	Appearance.addChangeListener(this.onAppThemeChanged);
	};
	componentWillUnmount() {
	Appearance.addChangeListener(this.onAppThemeChanged);
	};

is it correct to call addChangeListener in response to componentDidMount and componentWillUnmount?

[chrisglein]

Yep, that's wrong. Should be a removeChangeListener. Whoops!

I'm just learning so apologies, but in the 'not-Windows' React Native there is no removeChangeListener
https://reactnative.dev/docs/appearance

and in the Windows codebase there is addListener and removeListeners with an 's'.
https://github.com/microsoft/react-native-windows/blob/b051774f5429ed49df69e0b85ae16cfae8c18922/vnext/codegen/NativeAppearanceSpec.g.h#L17

Is that relevant?
