Problem

Dart's SDK is supposed to be bundled when Flutter is downloaded according to the documentation:

> "The Dart SDK is bundled with Flutter; it is not necessary to install Dart separately"

However, I opened an existing Flutter project with Android Studio and it suggested me to either "Download Dart SDK" or "Open Dart settings":

Apparently, I need to "Open Dart settings" and tell Android Studio where to find the Dart' SDK. However, it can't find it within the flutter/ directory.

The Dart SDK lives inside the bin/cache/dart-sdk folder of the Flutter SDK. It will be downloaded the first time you run the flutter command, so may not exist if you've not yet run flutter.

The Dart's SDK is located at /flutter/bin/cache/dart-sdk

However, If Android Studio's flutter plugin is installed, the plugin needs to be told where flutter's SDK is located. Android Studio should be able to locate Dart's SDK afterwards:

I have downloaded flutter sdk via homebrew

For Mac OS: 10.14.5

Android Studio version : Arctic Fox 2020.3.1

Flutter sdk location is /usr/local/Caskroom/flutter/2.5.0/flutter

Dart location: /usr/local/Caskroom/flutter/2.5.0/flutter/bin/cache/dart-sdk

After installing flutter however you choose.

1. run the following command > flutter sdk-path

2. In Android-Studio select File->Setting->Languages & Frameworks->Flutter (assuming you have installed teh flutter plugin)

3. Populate the "Flutter SDK path:" with the result from (1).

4. Click apply. The Dart SDK should automatically get populated.

For my installation the values are:

> Flutter SDK path: /home/andrew/snap/flutter/common/flutter

> Dart SDK path: /home/andrew/snap/flutter/common/flutter/bin/cache/dart-sdk

If you installed Dart on Windows via Chocolatey, you will find it on C:\tools\dart-sdk

Run brew info flutter

Then you get the path: e.g. /opt/homebrew/Caskroom/flutter/2.5.3

And there the bin/cache has the dartk-sdk:

/opt/homebrew/Caskroom/flutter/2.5.3/flutter/bin/cache/dart-sdk

I have faced this issue,

1. Go to the folder where you have downloaded flutter and then delete the flutter folder.

2. Go to your download folder and where you have downloaded the flutter the first time.

3. Extract this file again where you have deleted the flutter...

This is working for me.

If you have the flutter SDK installed.

Run:

flutter doctor -v

The first line will show the install path.

Sometimes it is the build directory that he cannot create, suddenly devtools crashes, you can simply recreate it in $HOME/.pub-cache/hosted/pub.dartlang.org/devtools-your-version, then give it the right rights with for example sudo chown -R $USER:$USER $HOME/.pub-cache/hosted/pub.dartlang.org/devtools-your-version/build after re-creating the build directory
