flutter_stripe is not showing keyboard on android

I am using flutter_stripe plugin for stripe payment. It is working on IOS but on android i am getting this error when i open payment screen.

Caused by: android.view.InflateException: Binary XML file line #22 in com.app.ss:layout/card_input_widget: Error inflating class com.google.android.material.textfield.TextInputLayout

Card payment is simple screen from example of flutter_stripe

Column(
              children: [
                Padding(
                  padding: EdgeInsets.all(16),
                  child: CardField(
                    onCardChanged: (card) {
                      setState(() {
                        _card = card;
                      });
                    },
                  ),
                ),
                Padding(
                  padding: EdgeInsets.symmetric(horizontal: 16),
                  child: LoadingButton(
                    onPressed: _card?.complete == true ? _handlePayPress : null,
                    text: 'Pay',
                  ),
                ),
              ],
            ),
