Keyboard is not showing on clicking on TextFormField in flutter android-CodePudding

I'm using TextFormField in flutter app. In my app everywhere It's working fine, But just in one screen it giving me an error. When I click on TextFormField then Keyboard opened and instantly hide automatically. Here is my code for TextFormField.

TextFormField(
                      controller: offerController,
                      maxLines: 1,
                      keyboardType: TextInputType.number,
                      textInputAction: TextInputAction.next,
                      style: GoogleFonts.arimo(
                        textStyle: const TextStyle(
                          color: Color(ColorConstants.TEXT_COLOR_GREY),
                          fontSize: 14.0,
                          fontWeight: FontWeight.w400,
                        ),
                      ),
                      decoration: InputDecoration(
                        border: InputBorder.none,
                        enabledBorder: InputBorder.none,
                        hintText: "Add the Offer Value",
                        hintStyle: GoogleFonts.arimo(
                          textStyle: const TextStyle(
                            color:
                            Color(ColorConstants.COLOR_BFBFBF),
                            fontSize: 14.0,
                            fontWeight: FontWeight.w400,
                          ),
                        ),
                      ),
                    )

Add this to your textFormField.

  FilteringTextInputFormatter.digitsOnly,
],
