How to run Flutter SDK on windows without Android Studio

Guys I use Mac but it will help fellows who use Windows PCs. This a great journey for anyone there who wants to become a flutter developer

Start by opening the Command prompt (cmd) <windows-key> + R then type cmd

Create the working Dir

It's better to keep everything in one directory considerC:\Android as main working directory

cd C:\
mkdir Android
cd Android

Installing OpenJDK 8

Download Windows binaries from the following URL:
https://github.com/AdoptOpenJDK/openjdk8-binaries/releases/download/jdk8u202-b08/OpenJDK8U-jdk_x64_windows_hotspot_8u202b08.zip

Other releases:

https://github.com/AdoptOpenJDK/openjdk8-binaries/releases

Extract it and rename the internal folder “jdk8u202-b08” to “OpenJDK” and copy it under “C:\Android” folder, the path will look like below:

C:\Android\openjdk

Installing Flutter SDK

Download flutter SDK latest version from the following URL:
https://flutter.io/docs/get-started/install/windows
Extract it, look for the folder with the name “flutter” to C:\Android folder, so the full path will be:

C:\Android\flutter

Installing Android command tools

Download Windows version of Android command tools from the following URL:
https://developer.android.com/studio/#command-tools
extract it and rename the “tools” folder to “SDK”, then copy it under C:\Android folder, the path will look like below:

C:\Android\sdk

Set Some Environment variables

We need to define some environment variable which let the above tools know how to contact each other, form command prompt run these commands, one by one:

setx JAVA_HOME “C:\Android\openjdk”
setx ANDROID_HOME “C:\Android”
setx ANDROID_SDK_ROOT “C:\Android\sdk”
setx path “%path%;”C:\Android\sdk;C:\Android\sdk\bin;C:\Android\flutter\bin”

Download Android SDK

As you may already know the Flutter are based on Android SDK to work, so we need to download system images, platform tools, build tools, platforms, and emulator, by running the following commands:

sdkmanager “system-images;android-27;default;x86_64”
sdkmanager “platform-tools”
sdkmanager “build-tools;27.0.3”
sdkmanager “platforms;android-27”
sdkmanager emulator

Note1: the date I write this tutorials the latest version of the above images was 28, but I downloaded the previous one, so I can develop app for wider range of Android OS versions, you can run the command sdkmanager --list to see available images and choose whatever you want.

Note2: Make sure to accept any license that appear by pressing y then Enter, or nothing will be downloaded.

Accept the licenses

Android SDK images have licenses that need to be accepted, you do that with the command:

sdkmanager — -licenses

just press y then Enter for for every license.

Configure Flutter

configure flutter to know the dir of the Android SDK path

flutter config — -android-sdk C:\Android\

Create the Emulator

Create a new emulator with the name “nexus” or choose the name you want:

avdmanager -s create avd -n nexus -k “system-images;android-27;default;x86_64”

answer with [no] to the showed question.

Run the emulator

flutter emulators --launch nexus

Moment of truth

flutter doctor -v

This command should give all green and ok, ignore the Android Studio complain, since this lesson is all about ignoring it in the first place.

Test flutter code

cd C:\Android\flutter\examples\hello_world
flutter run

[Extra] Other Good Emulator commands

Run emulator using emulator command, it should be executed from inside C:\Android\emulator

cd C:\Android\emulator
emulator -avd nexus

This command is good to see error messages

Create an emulator based on real device features

avdmanager -s create avd -n latest -k “system-images;android-27;default;x86_64” -d 30

you need to change the 30 with any other device id, you can see all available devices with the command:

avdmanager list device

Delete existed virtual emulator

avdmanager delete avd -n nexus

List all already created virtual emulators

avdmanager list avd
