How to Prevent React Native Text from Overflowing and Achieve Centered Text Within a Specific Width?

React Native Text Truncating Issue: A Comprehensive Solution

The issue described in the prompt arises when text within a React Native element extends beyond its intended boundaries, causing it to overflow off the screen. To address this issue and maintain a centered text layout within a specified width, such as 80% of its parent element, we need to leverage the capabilities of flexbox.

The code provided in the prompt introduces several React Native elements nested within each other, with specific styles applied to each. The text element in question, defined with numberOfLines={5}, restricts the number of lines displayed on the screen. However, it fails to prevent the text from exceeding the desired width.

The solution involves modifying the flex property of the parent View that contains the text element and adjusting its flexWrap setting. By setting flexWrap to 'wrap', we allow the text element to wrap onto multiple lines, preventing it from overflowing off the screen. Additionally, we set flexShrink to '1' to ensure that the text element shrinks when its parent View has limited space.

Here's the updated code:

<View style={{flex: 1, flexDirection: 'column', justifyContent: 'flex-start', backgroundColor: 'grey'}}>
  <View style={{flex: 0.5, flexDirection: 'column', alignItems: 'center', backgroundColor: 'blue'}}>
    <View style={{flex: 0.3, flexDirection: 'column', alignItems: 'center', justifyContent: 'center', flexWrap: 'wrap', flexShrink: 1}}>
      <Text style={{backgroundColor: 'green', fontSize: 16, color: 'white', textAlign: 'center', flexWrap: 'wrap'}}>
        Here is a really long text that you can do nothing about, its gonna be long wether you like it or not, so be prepared for it to go off screen. Right? Right..!
      </Text>
    </View>
  </View>
  <View style={{flex: 0.5, flexDirection: 'column', alignItems: 'center', backgroundColor: 'orange'}}>
    <View style={{flex: 0.3, flexDirection: 'column', alignItems: 'center', justifyContent: 'center', flexWrap: 'wrap', flexShrink: 1}}>
      <Text style={{backgroundColor: 'green', fontSize: 16, color: 'white', textAlign: 'center', flexWrap: 'wrap'}}>
        Some other long text which you can still do nothing about.. Off the screen we go then.
      </Text>
    </View>
  </View>
</View>

With these modifications, the text will remain confined within the specified width while wrapping onto multiple lines to fit the available space. This approach dynamically adjusts to various screen sizes while maintaining the desired text layout.
