How’s the Error Looks Like?

Here’s how the error looks like when you try to run the cloned project from Github.

Why Did you Get this Error?

This happened because you are trying to run a project which was not originally created in your machine. So probably the one who created the project might have a different Dart SDK path in his/her machine.

Steps to Fix Dart SDK is not Configured Error

To fix the Dart SDK is not Configured error, first of all, you must obtain the Flutter installation path and then figure out the dart SDK path. Then you can simply enable the Dart support for the project and let the Android Studio know about your Dart SDK path.

Here are the steps to fix the Error:

1. Open the terminal (in Mac/Linux) or command prompt (Windows)
2. Write which flutter. Copy the Flutter installation path.
3. Open Android Studio,
   • For Windows/Linux: Go to File->Settings->Language & Framework->Dart.
   • For Mac: Click Android Studio on top -> Preferences -> Languages & Framework -> Dart.
4. Checkmark the “Enable Dart support for the project…”
5. In Dart SDK Path, enter the previously copied path and replace the flutter in the end with cache/dart-sdk. So it should look something like this /Users/pinkeshdarji/Data/Development/flutter/bin/cache/dart-sdk
6. Click Apply.
7. Click OK.

Update dart sdk

To update Dart SDK, you can follow these steps:

1. Open your terminal or command prompt.
2. Check the current version of Dart SDK installed on your system by typing the following command:cssCopy codedart --version
3. If a new version is available, you can download it from the official Dart website at https://dart.dev/get-dart.
4. Once you have downloaded the new version, extract it to a suitable location on your system.
5. Update your environment variables to point to the new version of the SDK. For example, on a Unix-based system, you can add the following line to your .bashrc or .bash_profile file:bashCopy codeexport PATH="$PATH:/path/to/dart-sdk/bin"
6. Save the changes to the file and close it.
7. Open a new terminal or command prompt window, and verify that the new version of Dart SDK is installed by typing the following command:cssCopy codedart --version

You should see the version number of the new SDK that you just installed.

2. If you have an older version of the Dart SDK, go to the Dart SDK downloads page and download the latest version for your operating system.
3. After downloading the latest version of the Dart SDK, extract the archive file to a directory of your choice.
4. Open your Flutter project in an IDE or code editor and update the Dart SDK path in your project configuration to point to the location where you extracted the new Dart SDK.
