How to Prevent Widget Shrink or Resize on Keyword Popup in Flutter
Introduction
Resizing or shrinkage of widgets is a common issue encountered by Flutter developers, particularly when dealing with keyword popups. This issue can lead to an unpleasant user experience and affect the overall appearance of the application. In this article, we will explore the causes of widget shrinkage and provide solutions on how to prevent it.
Understanding the Cause of Widget Shrinkage
Widget shrinkage occurs when the size of the widget is not properly defined, causing it to resize or shrink when the keyword popup is displayed. This can be due to the widget being wrapped in a layout that has a limited size, or when the widget is not provided with a fixed size.
Solutions to Prevent Widget Shrinkage
To prevent widget shrinkage, you can use the following solutions:
1. Using SizedBox
You can use the SizedBox widget to provide a fixed size to the widget. This will prevent the widget from resizing or shrinking.
“`dart
SizedBox(
width: 200,
height: 50,
child: Text(‘Keyword’),
)
“`
2. Using Container
You can use the Container widget to provide a fixed size to the widget. This will also prevent the widget from resizing or shrinking.
“`dart
Container(
width: 200,
height: 50,
child: Text(‘Keyword’),
)
“`
3. Using FittedBox
You can use the FittedBox widget to scale the widget to fit the available space. This will prevent the widget from resizing or shrinking.
“`dart
FittedBox(
child: Text(‘Keyword’),
)
“`
