                      height: MediaQuery.of(context).size.height - 50,
                      child: Column(

                          BuildLoginHeaderScreen(theme: theme),
                          Expanded(
                            child: PageView(

            ),
          ),
        ),
      );
    });
  }

You can go around using resizeToAvoidBottomPadding by wrapping appropriate part of your code with SingleChildScrollView . For example

child: SingleChildScrollView( 
      child: Column(
               mainAxisSize: MainAxisSize.max,
               children: <Widget>[
                    BuildLoginHeaderScreen(theme: theme),
                    Expanded(
                        child: PageView(
                             controller: _pageController,
                             children: <Widget>[
                                ... // contains two TextFormFields
                              ],
                            ),
                     ),
              ],
      ),

),

This will prevent pixel overflow when the keyboard reduces the view area.
