Setup Device to run the application (From flutter.io)
To prepare to run and test your Flutter app on an Android device, you’ll need an Android device running Android 4.1 (API level 16) or higher.
- Enable Developer options and USB debugging on your device. Detailed instructions are available in the Android documentation.
- Windows-only: Install the Google USB Driver
- Using a USB cable, plug your phone into your computer. If prompted on your device, authorize your computer to access your device.
- In the terminal, run the
flutter devices command to verify that Flutter recognizes your connected Android device.
- Start your app by running
By default, Flutter uses the version of the Android SDK where your
adb tool is based. If you want Flutter to use a different installation of the Android SDK, you must set the
ANDROID_HOME environment variable to that installation directory.
Set up the Android emulator
To prepare to run and test your Flutter app on the Android emulator, follow these steps:
- Enable VM acceleration on your machine.
- Launch Android Studio>Tools>Android>AVD Manager and select Create Virtual Device.
- Choose a device definition and select Next.
- Select one or more system images for the Android versions you want to emulate, and select Next. An x86 or x86_64 image is recommended.
- Under Emulated Performance, select Hardware – GLES 2.0 to enable hardware acceleration.
- Verify the AVD configuration is correct, and select Finish.For details on the above steps, see Managing AVDs.
- In Android Virtual Device Manager, click Run in the toolbar. The emulator starts up and displays the default canvas for your selected OS version and device.
- Start your app by running
flutter run. The connected device name is
Android SDK built for <platform>, where platform is the chip family, such as x86.
The tar command in Linux is used to compress or create an archive of a directory with .tar.gz or .tgz archive files, they are also called “tarballs”.
tar -zcvf archive-file-name.tar.gz source-directory-name
Here tar is creating a archive named “archive-file-name.tar.gz” of “source-directory-name”.
-z = Compress the archive with gzip
-c = Creates a new .tar archive file
-v = Verbose, show .tar file progress
-f = Archive File name
Exclude particular directory or file
To exclude a file or directory from being added in the archive use –exclude option
tar -czvf archive-file-name.tar.gz /images/wallpaper --exclude /images/wallpaper/dogs
Compress multiple directories in single archive
tar -czvf archive-file-name.tar.gz /images/wallpaper /home/deven/Documents/notes.txt
You can add any no of directories or files you want to achive
How to Extract Archive
tar -xzvf archive-file-name.tar.gz
As you can see the only difference between creating an archive and extracting an archive is -x switch replace -c switch.
