When developing Flutter applications, encountering red text with yellow underlines below might be a common issue. This usually happens when text widgets are not properly wrapped within a Scaffold or any material widgets. In this blog, we’ll explore the reasons behind this issue and provide a practical solution using real Flutter code.
Understanding Red text and Yellow underlined below Text
The red text with yellow underlines indicates a UI issue in your Flutter application. This occurs when there is a missing or improperly placed Scaffold widget in your widget tree. Each page in Flutter should have a Scaffold or another material widget as its parent, ensuring a proper material design structure.
The Problem: Lack of Scaffold
Consider the following scenario where a text widget is not properly wrapped within a Scaffold:
import 'package:flutter/material.dart';
class MyRedTextPage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Text(
'This is red text with a yellow underline!',
style: TextStyle(color: Colors.red, decoration: TextDecoration.underline),
);
}
}
In this example, the text widget is not wrapped with a Scaffold, causing the red text with a yellow underline issue.
The Solution: Wrapping with a Scaffold
To resolve this issue, ensure that your widget tree includes a Scaffold. Here’s an updated version of the code with a Scaffold:
import 'package:flutter/material.dart';
class MyRedTextPage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Red Text Issue'),
),
body: Center(
child: Text(
'This is red text with a yellow underline!',
style: TextStyle(color: Colors.red, decoration: TextDecoration.underline),
),
),
);
}
}
In this example, we’ve wrapped the Text widget within a Scaffold, providing the necessary material structure for the page.
The Scaffold widget in Flutter provides a basic structure for material design layouts. It includes features like an AppBar for the top, a body for the main content, and other elements like a floating action button. When you encounter the red text with yellow underlines issue, it’s an indication that the text is not properly embedded within a material widget.
By wrapping your layout with a Scaffold, you ensure that the text and other UI elements are part of a material design structure, eliminating the red text issue.
