Where is Databases are stored?

When you create an SQLite DB programmatically, did you thought about the physical location of the DB? If you are coming from web development, you might look into project explorer for a file with the extension ‘db’. But it’s not in the project directory.

_initDatabase() async {
    ...
    String dbPath = join(dataDirectory.path, _databaseName);
    print('db location : '+dbPath);
    ...
  }

Now to see the printed output, If you are on VS Code, open Debug Console( from the view menu ). In my case, it prints as follows.

Connect to the SQLite DB

Now connect to the emulator through adb commands. As per android.developer, It a command-line tool, that lets you communicate with a device/ emulator. this tool will be there inside the platform-tools folder in your android SDK path. SDK path will be shown in android studio > sdk manager.

Now navigate inside the sdk location and then inside the platform-tools folder. where you could see adb.exe. Execute following command from the command prompt.

# View all of your emulator
adb devices
# Connect to your selected emulator
adb -s [emulator_name] shell

Now find your package name. It’s there in AndroidManifest.xml[/android/app/src/main/AndroidManifest.xml] file as package attribute.

Now run as the package. from the previous command prompt.

run-as [package_name]
# [package_name] = com.example.sqlite_crud


# Now navigate inside the folder where the db is stored
# which is the location printed from our app
cd [db_path]
# [db_path] - '/data/user/0/com.example.sqlite_crud/app_flutter'

# Connect to the db using sqlite3
sqlite3 [db_file]
# [db_file] : ContactData.db

# Now execute sql queries to view data inside the db.
# select * form contacts;

Hope you find this helpful. End.
