Build a flutter app in WSL2

Install, build and debug a flutter app in WSL2 (Windows Subsystem for Linux).

Linux setup

To install the JDK, execute the following command, which will also install the JRE:

sudo apt install default-jdk

Add the following two lines to /etc/profile (setting the JAVA_HOME environment variable):

export JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"
export PATH="$JAVA_HOME/bin:$PATH"

Open a new terminal window to automatically source the file.

For Linux desktop development, you need the following in addition to the Flutter SDK:

sudo apt install clang cmake ninja-build pkg-config libgtk-3-dev liblzma-dev

Refer to Microsoft's instructions below.

mkdir -p $HOME/Downloads && cd "$_"

Download the latest stable release of the Flutter SDK (Right-click and select “Copy link” to copy the address of the archive.):

wget https://storage.googleapis.com/flutter_infra_release/releases/stable/linux/flutter_linux_3.7.9-stable.tar.xz

Create an Applications directory if it doesn’t already exist, and navigate to it.

mkdir -p $HOME/Applications && cd "$_"

Extract the Flutter files from the archive in the Downloads directory to the Applications directory.

tar xfv $HOME/Downloads/$(ls -d $HOME/Downloads/flutter*.tar.xz | xargs basename)

Run the following command to see if there are any dependencies you need to install to complete the setup (for verbose output, add the -v flag):

flutter doctor

Add the following line to .bashrc:

export PATH="$HOME/Applications/flutter/bin:$PATH"

Open a new terminal window to automatically source the file (or run source .bashrc)

flutter doctor --android-licenses
