Red text and Yellow underlined below Text in Flutter

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.
