For Linux desktop development, you need the following in addition to the Flutter SDK:
Clang
CMake
GTK development headers
Ninja build
pkg-config
libblkid
liblzma
Step 1: Pls install these dependencies using:
1
sudo apt-get install clang cmake ninja-build pkg-config libgtk-3-dev libblkid-dev liblzma-devAlso, check for the existence of open jdk 8:

$ java -version
openjdk version "1.8.0_275"
OpenJDK Runtime Environment (build 1.8.0_275-8u275-b01-0ubuntu1~20.04-b01)
OpenJDK 64-Bit Server VM (build 25.275-b01, mixed mode)
If Open Jdk is not available install it using:
1
2
sudo apt-get install openjdk-8-jdk
sudo update-alternatives --config javaAfter running “sudo update-alternatives --config java” we have to select the number which contain jdk-8.
Export the environment variable - JAVA_HOME as follows:
1
export JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64"Also, add the above line as the last line in the file: ~/.bashrc
Step 2: Change directory to /usr/local:

$ whoami
ubuntuSince, Our login user is: ubuntu
Step 5: Change the ownership of the flutter repo directory to current user: ubuntu

flutter channel master
flutter upgrade -fStep 9: Run the following command to see if there are any dependencies you need to install to complete the setup
1
flutter doctorStep 10: Optionally, pre-download development binaries:
The flutter tool downloads platform-specific development binaries as needed. For scenarios where pre-downloading these artifacts is preferable (for example, in hermetic build environments, or with intermittent network availability), iOS and Android binaries can be downloaded ahead of time by running:
1
flutter precacheStep 11: Enable Linux Deskop
1
2
flutter config --enable-linux-desktop
Step 12: Step a directory to store flutter projects:
1
2
mkdir /opt/flutter-projects/
cd /opt/flutter-projects/Step 13: Create our first flutter app using the command:
1
2
flutter create myapp
cd /opt/flutter-projects/myappStep 14: Run our flutter app:
