A Flutter package to build widgets that can be attached to the soft keyboard.




  • An alternative to Scaffold's resizeToAvoidBottomInset, with animations.
  • Control the animations that should happen when the soft keyboard is shown and hidden with a transition builder.
  • Animate the shrinkage and expansion of the page when the soft keyboard is shown and hidden, matching the platform soft keyboard animation.
  • Easily add permanent page footers that can be attached to the top of the soft keyboard.


This package exposes a FooterLayout stateless widget and a KeyboardAttachable stateful widget.

FooterLayout is a widget that can lay out a child widget above a footer. It does that by positioning a footer widget at the bottom of the available space first, and then positioning a child widget in the remaining space.

    Widget build(BuildContext context) => FooterLayout(
          footer: MyFooterWidget(),
          child: PageMainContent(),

KeyboardAttachable is a widget that adds space below its baseline when the soft keyboard is shown and hidden with an animation that matches that of the platform keyboard. This widget can be used to animate its child when the soft keyboard is shown or hidden, so that the child widget appears to be attached to the keyboard.

You can combine these two widgets by passing a KeyboardAttachable widget as the footer of a FooterLayout to create a page that shrinks and expands when the soft keyboard appears and disappears, with an animation that matches the platform keyboard animation. Additionally, you can pass a child widget to your KeyboardAttachable to have a footer in your page that attaches itself to the soft keyboard when shown.

Warning: In order for this to work with animations, the resizeToAvoidBottomInset parameter of the Scaffold above the page has to be false. In addition to that, when there are SafeAreas involved the layout, it is recommended to set their maintainBottomViewPadding property to true in order for the animations to run smoothly, like so:

/// Builds a [Scaffold] that lays out a footer at the bottom of the page.
class KeyboardAttachablePage extends StatelessWidget {
  Widget build(BuildContext context) => Scaffold(
        resizeToAvoidBottomInset: false,
        appBar: AppBar(title: const Text("Keyboard Attachable demo")),
        body: SafeArea(
          maintainBottomViewPadding: true,
          child: FooterLayout(
            footer: KeyboardAttachableFooter(),
            child: ColorsList(),
