Start Circular Animation from/to specific Button

If you would like the circular animation to start from/to a button/view on your ui automatically, you can do the following

import switchTheme from 'react-native-theme-switch-animation';

<TouchableOpacity
  onPress={(e) => {
    e.currentTarget.measure((x1, y1, width, height, px, py) => {
      switchTheme({
        switchThemeFunction: () => {
          setTheme(theme === 'light' ? 'dark' : 'light');
        },
        animationConfig: {
          type: 'circular',
          duration: 900,
          startingPoint: {
            cy: py + height / 2,
            cx: px + width / 2,
          }
        },
      });
    });
  }}
/>

Trouble shooting

[iOS] Artifact for some components with border

https://github.com/WadhahEssam/react-native-theme-switch-animation/assets/24798045/8ad14c41-8757-4c21-b7e7-bf47b23e7f8b

this can be solved by adding a borderRadius of any value more than 1.2 for the component

<View
  style={{
    borderWidth: 1,
    borderColor: theme === 'light' ? 'black' : 'white',
    borderRadius: 1.2, // -> Add This
    padding: 20,
    marginBottom: 20,
  }}
>
  <Text
    style={{
      color: theme === 'light' ? 'black' : 'white',
    }}
  >
    test
  </Text>
</View>
