Using react-native and styled-components with TypeScript,

I want to know what is the typing of props.style in styled.TouchableOpacity component in order to be able to wrap style on it, ex:

const Boutton = styled.TouchableOpacity

const Test = () => <Button />

const WrapTest = styled(Test)({
 // add styled
})

In order to do that, I must have the proper type to satisfy TypeScript:

const Test = (props) => <Button style={props.style} />

I have tried to use style?: StyleProps<ViewStyle>, but it gives me the following error:

No overload matches this call.

This is where I want to setup the props: https://github.com/pass-culture/pass-culture-app-native/blob/master/src/ui/components/buttons/AppButton.tsx#L24

What is the Typing of props.style for styled.TouchableOpacity in react-native ?

CodePudding user response：

Assuming react-native version is 0.64.2, the answer should be StyleProp<ViewStyle> | undefined.

TouchableOpacity extends TouchableOpacityBase, which has the type of TouchableOpacityComponent, which extends React.Component<TouchableOpacityProps>.

If you look into TouchableOpacityProps, you will see that it extends TouchableWithoutFeedbackProps, which has its style prop typed with : StyleProp<ViewStyle> | undefined.

(Following the question description's update) Furthermore, you need to use the TouchableOpacity component directly imported from react-native : styled(TouchableOpacity) instead of styled.TouchableOpacity.

CodePudding user response：

The Type of a style prop is ViewStyle (like it is written in the docs style?: StyleProp<ViewStyle>). This is generally true for basic components, only for the <Text> there is TextStyle.

Does this answer your question?
