Flutter is a popular open-source mobile application development framework. It allows developers to easily create beautiful, responsive, and high-performance mobile applications for iOS, Android, and the web. Flutter is known for its powerful features and intuitive API, which makes it easy to build high-quality apps with minimal effort. However, not all apps require the latest version of Flutter, and sometimes, it may be necessary to downgrade your Flutter version for compatibility or other reasons. In this article, we’ll discuss how to downgrade your Flutter version and provide some code examples to help you get started.
Why would you downgrade Flutter?
Before we dive into the process of downgrading Flutter, let’s first understand why one would want to do so. There are primarily two reasons:
-
Compatibility: Some packages or plugins may only work with specific versions of Flutter. If you’re working on a project with an older package, you might need to downgrade Flutter to make sure they work together seamlessly.
-
Stability: Upgrading to the latest Flutter version may not always be the best option for your app. While upgrading may introduce some new features and enhancements, it may also introduce bugs or instability that could affect your app's performance. By downgrading, you can ensure that your app runs smoothly and without any hiccups.
Now that we know why we might need to downgrade Flutter, let’s dive into how to do it.
How to Downgrade Flutter?
Downgrading Flutter is a fairly simple process, which involves running a few commands in your terminal. Before you get started, make sure you backup any changes you’ve made to your project so that you don’t lose any work. Additionally, keep in mind that the steps may vary slightly depending on your operating system.
Step 1: Check your current version of Flutter
To find out which version of Flutter you're currently running, run the following command in your terminal:
flutter --version
This command will display your current version of Flutter, including the Flutter, Dart, and Engine versions.
Step 2: Choose the version you want to downgrade to
Now that you know which version of Flutter you're currently running, you can choose the version you want to downgrade to. You can find a list of all available Flutter versions on the Flutter releases page. Choose the version you need to downgrade to and make a note of the version number.
Step 3: Uninstall your current version of Flutter
Before installing a different version of Flutter, you’ll need to uninstall your current version. To do this, run the following command in your terminal:
flutter downgrade
This command will prompt you to select the version you want to downgrade to. Enter the version number you noted earlier and hit Enter. Flutter will then remove your current version of Flutter and install the requested version.
Step 4: Confirm the version
Once the installation is complete, you can verify that you have successfully downgraded to the desired version by running the same command as in step 1.
flutter --version
Congratulations! You’ve successfully downgraded Flutter to your desired version.
Code Examples
Here are a few examples to demonstrate the process of downgrading Flutter using the command line.
Example 1: Downgrade to the previous Flutter version
If you want to downgrade to the previous version of Flutter, you can use the following command in your terminal:
flutter downgrade
Flutter will then prompt you to choose the version you want to downgrade to.
Example 2: Downgrade to a specific version
If you want to downgrade to a specific version of Flutter, use the following command in your terminal:
flutter downgrade <version>
Replace
Example 3: Downgrade and reinstall a specific version
If you want to downgrade to a specific version and reinstall it, use the following commands in your terminal:
flutter clean
flutter downgrade <version>
flutter packages get
flutter pub upgrade
These commands will first clean up your existing project, followed by downgrading to the desired version, getting the required packages, and upgrading your project.
Conclusion
In conclusion, downgrading Flutter can be necessary to maintain compatibility between your app and the packages or plugins you're using, or for ensuring the stability of your app. We hope this article has provided a clear and concise guide to help you downgrade your Flutter version with ease. Remember to always backup your project before making any significant changes and test your app thoroughly after downgrading.

Flutter:
Flutter is a UI toolkit, developed by Google, used to build mobile, web, and desktop applications. It is an open-source framework, based on Dart programming language, used to create high-performance and visually-appealing applications. Flutter is highly popular among developers due to its fast development scope, cross-platform functionality, UI flexibility, and a wide range of pre-built widgets. Flutter provides a Hot Reload feature, allowing developers to view real-time changes to their applications. This feature boosts efficiency and productivity, making it an ideal choice for mobile app development.
Flutter Package:
Flutter packages or plugins are pre-built, ready-to-use modules of code that provide extra functionality to your Flutter apps. These packages enable developers to speed up their development process, enhance their app’s functionality, and reduce errors. There are a variety of Flutter packages available on platforms like pub.dev, Flutter's official package repository. These packages cover a wide range of areas, including, but not limited to, UI, navigation, web services, state management, animations, and maps. Developers can also create their own Flutter packages and share them in the repository. This encourages reusability and sharing of code in the community.
Flutter Downgrade:
Flutter downgrade is the process of reverting to an earlier version of Flutter. This process is usually required to maintain compatibility between your app and packages or plugins you're using, or for ensuring the stability of your app. The process involves running a few commands in the terminal and selecting the version you want to downgrade to. Before downgrading, it is always recommended to backup your project and test your app thoroughly after downgrading.
In conclusion, Flutter is a powerful and versatile UI toolkit, providing developers with numerous pre-built widgets and packages to build high-performance and feature-rich mobile applications. Flutter downgrade is a process to revert to an earlier version of Flutter, which can assist developers in maintaining compatibility with packages and plugins, and enhance the stability of their app. With a vast community, rich ecosystem, and flexible architecture, Flutter will continue to be on top of the developer's choice for building cross-platform applications.
