Type Script - React Native: " ViewStyle " type issue

When I pass the parameter:

defaultButtonTextDark: {     fontWeight: 'bold',     color: 'white',     fontSize: 16,   },

into ThemeManager function :

const ThemeManager = (darkStyle: ViewStyle, lightStyle: ViewStyle) => {  DO SOMETHING...}

So it shows me the following error:

Type '{ fontWeight: "bold"; color: string; fontSize: number; }' has no properties in common with type 'ViewStyle'.ts(2559).

way of use the function:

<Text style={ThemeManager(styles.defaultButtonTextDark, styles.defaultButtonText)}>return default</Text>

What is the way to solve this type issue ?
