In above code,
I need to eliminate sizebox 70 because view should be center vertical & button should be bottom aligned so size box 120 also need to eliminated. how to fix this two problem in above code.
I m new to flutter i have tried above code with basic knowledge any help improving above code is appreciated.
Any help is appreciated!
Instead of using a Row(), you should have used a Stack(), with alignment: AlignmentDirectional.center.
Try This....
class Otp extends StatefulWidget {
@override
State<StatefulWidget> createState() {
return OtpPage();
}
}
class OtpPage extends State<Otp> {
String assetNameArrow = 'images/ic_back.svg';
String assertOtp = 'images/otp_sms.svg';
int backspaceClick = 0;
String otpError = "";
bool isHideOTP = true;
bool isTextFiledFocus = false;
String otp1 = "";
String otp2 = "";
String otp3 = "";
String otp4 = "";
String otp5 = "";
String otp6 = "";
FocusNode focusNodeOtp1 = FocusNode();
FocusNode focusNodeOtp2 = FocusNode();
FocusNode focusNodeOtp3 = FocusNode();
FocusNode focusNodeOtp4 = FocusNode();
FocusNode focusNodeOtp5 = FocusNode();
FocusNode focusNodeOtp6 = FocusNode();
