Installing Flutter

Go to https://docs.flutter.dev/get-started/install and select the OS that works for you

I’m working with Windows so I’ll step through what’s needed for that

Download the Flutter SDK by clicking the “flutter_windows_3.3.7-stable.zip” or whatever version it’s up to by the time you read this (approx 820MB)

Extract to c:\src

Add the c:\src\flutter\bin folder to your path (in the environment variables)

Open a command prompt (Press the Start Button  and type CMD[Enter])

Type “cd \src\flutter” to get to the flutter directory

Type “flutter doctor”. This will check the install is good and report any problems. In my case, I got the following: –

To resolve the “Unable to locate Android SDK” problem, install Android Studio from https://developer.android.com/studio/index.html

Once the Android studio install has completed, run “flutter doctor” again and you’ll see this: –

To solve the cmdline-tools problem, open the SDK Manager in Android Studio and install the Android SDK Command-line Tools as shown in the screenshots below: –

…and this is easily solved by typing “flutter doctor –android-licenses” and pressing [Enter]

Follow the prompts and accept the licenses and you’ll now see a clean bill of health

Ok. You now have Flutter installed!
