A StyleSheet is an abstraction similar to CSS StyleSheets
Create a new StyleSheet:
var styles = StyleSheet.create({
container: {
borderRadius: 4,
borderWidth: 0.5,
borderColor: '#d6d7da',
},
title: {
fontSize: 19,
fontWeight: 'bold',
},
activeTitle: {
color: 'red',
},
});
Use a StyleSheet:
<View style={styles.container}>
<Text style={[styles.title, this.props.isActive && styles.activeTitle]} />
</View>
Code quality:
- By moving styles away from the render function, you're making the code
easier to understand.
- Naming the styles is a good way to add meaning to the low level components
in the render function.
Performance:
- Making a stylesheet from a style object makes it possible to refer to it
by ID instead of creating a new style object every time.
- It also allows to send the style only once through the bridge. All
subsequent uses are going to refer an id (not implemented yet).
