@YajanaRao
Thanks for the changes! CI seems to be failing, so could you make the following changes?

1. run yarn lint --fix to apply fix for lint error
2. in ci.yml file, under android:, add a step to install and build packages in the example directory after yarn install
   it should look like this:

      - name: Install Dependencies
        run: yarn
      - name: Install Example Dependencies
        run: cd example && yarn
      - name: Build android
        run: cd example && yarn build:android
      - name: Build Android Example App and Library
        run: cd example/android && ./gradlew clean assembleDebug

3. also in ci.yml file, under ios:, add a step to install and build packages in the example directory after yarn install

      - name: Install Dependencies
        run: yarn
      - name: Install Example
        run: cd example && yarn
      - name: Build ios
        run: cd example && yarn build:ios  
      - name: Pod install
        run: cd example && pod install --project-directory=ios
      - name: Run ios app
        run: cd example && yarn ios

@Naturalclar I have done the changes you requested. yarn lint --fix Did not do any changes to commit.

@YajanaRao thanks for the changes!
sorry, there was one more fix that needed to be done.
the default java version in ci is 8, but current android build required java 11, so android job needs to be set up to use java 11.

Could you add actions/setup-java in the ci and make it use java 11?

setup should look something like this:

  android:
    runs-on: ubuntu-18.04
    strategy:
      matrix:
        node-version: [16]
        java-version: [11]        
    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-node@v1
        with:
          node-version: ${{ matrix.node-version }}
      - uses: actions/setup-java@v3
        with:
          distribution: 'zulu'
          java-version: ${{ matrix.java-version }}
