How to Display Text Over Two Lines in Flutter's AppBar

When developing mobile applications with Flutter, you might encounter a scenario when your AppBar needs to display a title that is longer than one line. This can lead to the text getting truncated, leaving users with an incomplete view due to the limitations of the display area. Fortunately, there is a simple solution to allowing your text to wrap onto two lines instead of being cut off.

Understanding the Problem

In the provided code, the AppBar is structured using a Row, which includes two images on either side of the title text. The title text is set to uppercase and has a defined font size. However, when the text exceeds a certain length, it gets truncated with an ellipsis ("..."), which is not ideal for user experience since users can't see the complete title.

Example of the Current Code Structure

Here is a simplified version of your current setup:

The Solution

To ensure that the title can wrap onto two lines, you need to make a small adjustment to your Text widget's properties by adding the maxLines property.

Conclusion

By adding maxLines: 2 to the Text widget, you allow the title text in the AppBar to expand to two lines instead of being truncated with an ellipsis. This change enhances usability, ensuring that users have a complete view of the title, regardless of its length.

Implement these changes in your Flutter application and improve your AppBar's presentation—your users will appreciate the clarity!
