                      child: Text('Email'),
                    ),
                  ),
                ),
              )

Solution

Just use Align for keeping always on head.

Container(
            decoration: new BoxDecoration(
                color: Colors.blue,
                borderRadius: new BorderRadius.only(
                  topLeft: const Radius.circular(40.0),
                  topRight: const Radius.circular(40.0),
                )),
            child: new Align(
              alignment: Alignment.topCenter,
              child: Padding(
                padding: EdgeInsets.symmetric(vertical: 0),
                child: Text('Email'),
              ),
            ),
          ),
