Widget not going to bottom of screen in Flutter?

flutter align bottom
flutter fixed bottom widget
flutter bottom sheet
flutter positioned
flutter set widget on bottom
flutter singlechildscrollview scroll to bottom
flutter offset widget
flutter floating widget

So I'm trying to get the REGISTER button to align on the bottom center of the screen. I'm relatively new to Flutter and am wondering if there is a way to do this easily, or do I need to rewrite a lot of code? Here's what I have so far. As you can see, I put it in an Align(), but it only goes to the bottom center of the filled area. I think what I have to do is make the outside Container() the height of the entire screen, but I also don't know how to do this. If you have a way to do this, please let me know. Thanks.

class LoginSignupScreen extends StatefulWidget {

  void _changeScreen() {
    setState(() {
      // sets it to the opposite of the current screen
      _register = !_register;
    });
  }

          Align(
            alignment: FractionalOffset.bottomCenter,

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

You will solve using Expanded widget.

        Expanded(
          child: Align(
            alignment: FractionalOffset.bottomCenter,
            child: MaterialButton(
              onPressed: () => {},
              child: Text(_register ? 'REGISTER' : 'LOGIN'),
            ),
          ),

How to set an element to bottom of SingleCildScrollView? · Issue , I have created a screen that works well with the columns, but I I have googled this problem and found this: Flutter - SingleChildScrollView interfering in columns But there Main problem is - I need to set Widget at bottom of Scrollable Not an issue. Contact GitHub · Pricing · API · Training · Blog · About. In this blog post, let’s check how to place a button at the bottom of the screen in Flutter. We need to use Align class to align widgets at the bottom, Align class has a property named alignment, that’s where we specify the desired position of the widget. Then we use Alignment class with the constant bottomCenter.

You can set the Container height to cover the entire screen as you mentioned and then just wrap your Align widget inside an Expanded widget, which will fill the available space.

Try this code:

Widget build(BuildContext context) {
    return Container(
      height: MediaQuery.of(context).size.height,
      child: Column(
        children: <Widget>[
          Padding(
            padding: const EdgeInsets.all(20),
            child: Row(
              mainAxisAlignment: MainAxisAlignment.center,
              children: <Widget>[
                ButtonBar(
                  children: <Widget>[
                    MaterialButton(
                      onPressed: _changeScreen,
                      child: Text('REGISTER'),
                    ),
                    MaterialButton(
                      onPressed: _changeScreen,
                      child: Text('LOGIN'),
                    ),
                  ],
                ),
              ],
            ),
          ),
          Padding(
            padding: EdgeInsets.all(20),
            child: Column(
              children: <Widget>[
                TextField(
                  decoration: InputDecoration(
                      border: InputBorder.none, hintText: 'E-MAIL'),
                ),
                TextField(
                  decoration: InputDecoration(
                      border: InputBorder.none, hintText: 'USERNAME'),
                ),
                TextField(
                  decoration: InputDecoration(
                      border: InputBorder.none, hintText: 'PASSWORD'),
                )
              ],
            ),
          ),
          Expanded(
            child: Align(
              alignment: Alignment.bottomCenter,
              child: MaterialButton(
                onPressed: () => {},
                child: Text(_register ? 'REGISTER' : 'LOGIN'),
