Unlocking the Power of Masking in React Native

What is Masking?

Masking involves using one digital element to modify or extract data from another digital element. In the context of React Native, masking can be used to create text and vector masks with image, gradient, and app element-based backgrounds.

Key Features of react-native-masked-view

• Cross-platform support: The library supports both Android and iOS platforms, making it easy to create masked views that work seamlessly across different devices.
• Element-type-independent masking: The library allows developers to use any valid React element as a mask, providing flexibility and creativity in designing masked views.
• Animations support: The library supports animations, enabling developers to create dynamic and engaging masked views that enhance the user experience.

Practical Examples of Masking in React Native

Text Mask with Background Texture

Create a text mask with a background texture to add visual interest to your app’s interface.

import React from 'react';
import { Text, View } from 'react-native';
import MaskedView from 'react-native-masked-view';

const TextMask = () => {
  return (
    <MaskedView
      style={{ flex: 1 }}
      maskElement={
        <Text style={{ fontSize: 24, fontWeight: 'bold' }}>
          Hello World!
        </Text>
      }
    >
      <View style={{ backgroundColor: 'orange', flex: 1 }}></View>
    </MaskedView>
  );
};

Vector Shape Masks

Use vector shapes as masks to create unique and engaging visual effects.

import React from 'react';
import { View } from 'react-native';
import MaskedView from 'react-native-masked-view';
import Svg from 'react-native-svg';

const VectorShapeMask = () => {
  return (
    <MaskedView
      style={{ flex: 1 }}
      maskElement={
        <Svg height="100%" width="100%" viewBox="0 0 100 100">
          <Circle cx="50" cy="50" r="40" fill="#000" />
        </Svg>
      }
    >
      <View style={{ backgroundColor: 'blue', flex: 1 }}></View>
    </MaskedView>
  );
};

Gradient Backgrounds

Use gradient backgrounds with masks to add depth and dimension to your app’s interface.

import React from 'react';
import { View } from 'react-native';
import MaskedView from 'react-native-masked-view';
import LinearGradient from 'react-native-linear-gradient';

const GradientBackgroundMask = () => {
  return (
    <MaskedView
      style={{ flex: 1 }}
      maskElement={
        <LinearGradient
          colors={['#ff0000', '#00ff00']}
          style={{ flex: 1 }}
        />
      }
    >
      <View style={{ backgroundColor: 'purple', flex: 1 }}></View>
    </MaskedView>
  );
};

Using Animations with Masks

Animations can be used with masks to create dynamic and engaging visual effects. By combining the react-native-masked-view library with the built-in animation API, developers can create stunning opener animations that enhance the user experience.
