Flutter text max length

Flutter Text Max Length

In Flutter, the Text widget does not have a specific property to limit the maximum length of text. However, you can achieve this by using various techniques and widgets.

1. Using substrings:

One approach is to use the substring method to extract a specific number of characters from the original text and display it within the Text widget.

  
    String originalText = "Lorem ipsum dolor sit amet consectetur adipiscing elit";
    String maxLengthText = originalText.length > 10 ? originalText.substring(0, 10) + "..." : originalText;
    
    return Text(maxLengthText);
  
  

2. Using the Flutter package – ‘flutter_truncate’

The ‘flutter_truncate’ package provides a truncate method that allows you to limit the number of lines or characters in a Text widget.

  
    String originalText = "Lorem ipsum dolor sit amet consectetur adipiscing elit";
    String maxLengthText = truncate(originalText, 10); // Limiting to 10 characters
    
    return Text(maxLengthText);
  
  

3. Using the Flutter package – ‘flutter_redux’

The ‘flutter_redux’ package provides a ‘MaxLengthTextField’ widget that allows you to set a maximum length for input text. You can use this widget to display a limited text as a non-editable field.

  
    String originalText = "Lorem ipsum dolor sit amet consectetur adipiscing elit";
    
    return MaxLengthTextField(
      maxLength: 10, // Limiting to 10 characters
      initialValue: originalText,
      enabled: false, // Non-editable field
    );
  
  

Choose the approach that best suits your use case and integrate it into your Flutter application to limit the maximum length of text.
