Introduction
In the world of Flutter app development, effectively handling dynamic text can be a challenge. Text that dynamically changes its length or content often requires manual adjustment to fit within limited space. However, Flutter offers a solution: the AutoSizeText widget. In this blog post, we will explore the capabilities of AutoSizeText, understand its usage, and provide a practical example to help you harness its power in your Flutter applications.
Understanding AutoSizeText
The AutoSizeText widget in Flutter automatically adjusts the font size of its text to fit within the available space. It eliminates the need for manual intervention and ensures that text remains readable and visually appealing, regardless of its length or the size of its container. With AutoSizeText, you can achieve a seamless and responsive text display that adapts to different screen sizes and content variations.
Example Usage
Firstly install the auto_size_text library by running the below code in the terminal 👇
flutter pub add auto_size_textTo demonstrate the usage of AutoSizeText, let's consider a scenario where you have a container with a fixed width, and you want to display a dynamically changing text within it.
Open the main.dart file and paste the below code inside it 👇
import 'dart:async';
import 'package:flutter/material.dart';
import 'package:auto_size_text/auto_size_text.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'AutoSizeText Demo',
debugShowCheckedModeBanner: false,
home: AutoSizeTextDemo(),
);
}
}
class AutoSizeTextDemo extends StatefulWidget {
const AutoSizeTextDemo({super.key});
@override
State<AutoSizeTextDemo> createState() => _AutoSizeTextDemoState();
}
class _AutoSizeTextDemoState extends State<AutoSizeTextDemo> {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
centerTitle: true,
title: Text('AutoSize Text Demo'),
),
body: Center(
child: Container(
width: 200,
child: AutoSizeText(
"Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industrys standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.",
style: TextStyle(fontSize: 24),
maxLines: 100,
overflow: TextOverflow.ellipsis,
),
),
),
);
}
}In the code above, we have a Container widget with a fixed width of 200 pixels. Inside it, we use AutoSizeText to display the Lorem Ipsum Text. We set the initial font size to 24 pixels using the TextStyle property. The maxLines property is set to 1 to ensure that the text stays within a single line, and the overflow property is set to TextOverflow.ellipsis, which adds an ellipsis (...) at the end if the text exceeds the available space.
As the text dynamically changes, AutoSizeText automatically adjusts the font size to fit within the 200-pixel width constraint. This ensures that the text remains visible and readable, regardless of its length.
Output
Here's the output of the above code 👇
Conclusion
The AutoSizeText widget in Flutter simplifies the process of dynamically fitting text within constraints, offering a seamless user experience across various screen sizes and content variations. By leveraging AutoSizeText, you can eliminate manual adjustments and enjoy automatic font size scaling, ensuring that your text remains accessible and visually pleasing.
