How to Manage Flutter Versions with FVM for Older Projects?

Managing multiple Flutter versions across different projects can be challenging, especially with older codebases. Using Flutter Version Management (FVM) ensures each project runs on the exact Flutter version it was developed with. FVM helps match the Flutter version specified in the project's pubspec.yaml file, which is crucial for compatibility. To get started with FVM, ensure Dart is installed and then install FVM globally. To set a specific Flutter version for a project, navigate to the project directory and use the command "fvm use <version>". This command installs the specified version if not already installed and creates an .fvm directory and dart tool configuration. To automate version management, create a .fvm configuration file in the project's root directory with the exact Flutter version required. This file allows developers to quickly set up their environment without manually changing versions. FVM can also manage Flutter channels, and it's essential to check channel and version compliance to ensure the project works smoothly. By following these steps, developers can ensure the proper setup and automate the version management process, minimizing compatibility issues and deprecations.
