                        child: const Icon(
                          Icons.lock_outline,
                          color: Colors.white,

                        ),
                    errorText: validate ? 'Password Can\'t Be Empty' : null,
                  ),
                  obscureText: _obscureText,
  
                ),
                TextField(
                  style: new TextStyle(color: Colors.white),

                        )),
                    // errorText:
                    // validate ? 'Password Can\'t Be Empty' : null,
                  ),
