How to downgrade Flutter SDK (Dart 1.x)

📝 Title: How to Downgrade Flutter SDK and Fix Your Broken Projects

🎯 Introduction

Have you recently upgraded your Flutter SDK only to find that your project has broken? Don't panic! We've got you covered. In this blog post, we will walk you through the step-by-step process of downgrading your Flutter SDK to use Dart 1.x, so you can get your project back on track.

⚠️ The Problem

You tried to revert back to a previous Flutter SDK version that utilized Dart 1.x by modifying the pubspec.yaml file. However, now your project fails to build, leaving you frustrated and stuck. So, what's the solution?

💡 The Solution

Before we jump into the downgrade process, let's make sure you have the Flutter SDK installed. If you don't, you can download it from the official Flutter website.

Now, let's get started with the downgrade:

1. Check Installed SDK Versions: Open your terminal and run the command flutter --version. Make sure to note down the current SDK version.

2. Uninstall the Current SDK: To uninstall the current version of the Flutter SDK, run flutter --version to find out where your SDK is installed. Then, delete that folder.

   📝 Note: Make sure to backup any important projects before proceeding.

3. Find the Desired SDK Version: Visit the Flutter Releases page on GitHub and locate the version that meets your criteria (Dart 1.x in this case). You can search for the specific version or look for the release with that information.

4. Download and Extract the Desired SDK Version: Once you've found the desired SDK version, download the zip file associated with it. Extract the contents to a new folder on your computer.

5. Set Flutter SDK Path: Open your terminal and run the following command, replacing {flutter_path} with the path to the newly extracted Flutter SDK folder:

   export PATH={flutter_path}/bin:$PATH

6. Verify the SDK Change: Run flutter --version again to ensure that the SDK version has been successfully changed.

7. Update Flutter Packages: Navigate to your project's root directory in the terminal, and run the command flutter packages get to fetch the dependencies specified in the pubspec.yaml file.

   📝 Note: If you encounter any errors during this process, ensure that your dependencies are compatible with the chosen Flutter SDK version.

🔧 Troubleshooting

If you still face issues after following the steps above, try the following additional troubleshooting steps:

• Check if any plugins or packages you're using in your project are not compatible with Dart 1.x. Visit their respective documentation or GitHub repositories to find compatible versions.

• Consider creating a new Flutter project and gradually migrating your codebase to the new project.

• Reach out to the Flutter community! Exploring the official Flutter GitHub repository, Reddit, or online forums can provide valuable insights and solutions.

📣 Conclusion
