  const [theme, setTheme] = React.useState('light');

  return (
    <Button
      title="Switch Theme"

        switchTheme({
          switchThemeFunction: () => {
            setTheme(theme === 'light' ? 'dark' : 'light'); // your switch theme function

Circular Example

switchTheme({
  switchThemeFunction: () => {
    setTheme(theme === 'light' ? 'dark' : 'light'); // your switch theme function
  },
  animationConfig: {
    type: 'circular',
    duration: 900,
    startingPoint: {
      cxRatio: 0.5,
      cyRatio: 0.5
    }
  },
});

switchTheme Function Props

| Name | Type | Description | | :------ | :------ | :------ | | switchThemeFunction | () => void | Adds the function you use in your app to switch themes, doesn't matter if you use redux/context/zustand/mobx or any other way | | animationConfig | AnimationConfig | Configuration for the animation -> type, duration, starting point (default is 'fade' with 500ms duration) |

startingPoint options

| Name | Type | Description | | :------ | :------ | :------ | | cx | number | Specifies starting x point for circular and inverted-circular animation (should not exceed your screen width) | | cy | number | Specifies starting y point for circular and inverted-circular animation (should not exceed your screen height) | | cxRatio | number | Specifies starting percentage of x point for circular and inverted-circular animation (should be number between -1 and 1) | | cyRatio | number | Specifies starting percentage of y point for circular and inverted-circular animation (should be number between -1 and 1) |

Start Circular Animation from/to speceific 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>
