How to Fix Vertical Divider Not Showing in Flutter App
Introduction
Flutter is a popular framework for building cross-platform mobile applications. However, developers may encounter issues while designing and building their apps, one of which is the vertical divider not showing in the Flutter app. In this post, we will discuss how to fix this issue and provide a comprehensive solution.
Understanding the Issue
The vertical divider is a crucial element in designing the UI of a Flutter app. It is used to separate different sections or widgets in the app. However, sometimes the vertical divider may not show up as expected, which can be frustrating for developers. To fix this issue, we need to understand the possible causes and then apply the necessary solutions.
Possible Causes
There are several reasons why the vertical divider may not be showing in a Flutter app. Some of the possible causes include:
– Incorrect use of the VerticalDivider widget
– Insufficient width or height of the parent widget
– Conflict with other widgets or elements in the app
Solution
To fix the issue of the vertical divider not showing in a Flutter app, we can use the following code example:
“`dart
import ‘package:flutter/material.dart’;
class VerticalDividerExample extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Row(
children: [
Container(
width: 100,
height: 100,
color: Colors.blue,
),
VerticalDivider(
thickness: 2,
color: Colors.black,
),
Container(
width: 100,
height: 100,
color: Colors.red,
),
],
),
);
}
}
“`
In this example, we are using the VerticalDivider widget inside a Row widget, which contains two Container widgets. The VerticalDivider widget is used to separate the two containers.
