When the keyboard appears, the Flutter widgets resize. How to prevent this?

Issue

I have a Column of Expanded widgets like this:

 return new Container(
      child: new Column(
        crossAxisAlignment: CrossAxisAlignment.stretch,
        children: <Widget>[
          new Expanded(
            flex: 1,
            child: convertFrom,
          ),
          new Expanded(
            flex: 1,
            child: convertTo,
          ),
          new Expanded(
            flex: 1,
            child: description,
          ),
        ],
      ),
    );

It looks like this:

convertFrom, includes a TextField. When I tap on this text field, the Android keyboard appears on the screen. This changes the screen size, so the widgets resize like this:

Is there a way to have the keyboard “overlay” the screen so that my Column doesn’t resize? If I don’t use Expanded widgets and hardcode a height for each widget, the widgets don’t resize, but I get the black-and-yellow striped error when the keyboard appears (because there isn’t enough space). This also isn’t flexible for all screen sizes.

I’m not sure if this is an Android-specific or Flutter-specific.

Solution

Updated Answer

resizeToAvoidBottomPadding is now deprecated.

The updated solution is to set resizeToAvoidBottomInset property to false.


Original Answer

In your Scaffold, set resizeToAvoidBottomPadding property to false.
