Flutter Upgrade Dart SDK

To upgrade the Dart SDK in your Flutter project, follow the steps outlined below:

Step 1: Check Current Dart SDK Version

Before upgrading, it’s always a good practice to check the current Dart SDK version used in your Flutter project. Open a terminal or command prompt and navigate to your project’s directory. Then execute the following command:

flutter --version

The output will display the current Flutter version along with the Dart SDK version.

Step 2: Upgrade Flutter

Make sure you have the latest Flutter version installed. To upgrade Flutter itself, execute the following command in the terminal:

flutter upgrade

This command will check for any available updates and upgrade Flutter to the latest stable version.

Step 3: Upgrade Dart SDK

After upgrading Flutter, you can proceed with upgrading the Dart SDK. Execute the following command:

flutter upgrade --force

The --force flag is used to force an upgrade of the Dart SDK even if it’s already up to date.

Step 4: Verify Dart SDK Upgrade

To verify that the Dart SDK has been successfully upgraded, run the following command in the terminal:

dart --version

The output should display the updated Dart SDK version.

Example

Let’s assume you want to upgrade the Dart SDK for a Flutter project located in /path/to/flutter_project. Here’s how the steps would look:

cd /path/to/flutter_project
flutter --version
flutter upgrade
flutter upgrade --force
dart --version

By following these steps, you will have successfully upgraded the Dart SDK in your Flutter project to the latest version.
