How do I scroll all content on top of keyboard?

Question

I want a container fix on top of the page and the rest of the screen should scroll up when the keyboard appears. I can make it scroll by using ListView but that way I can not fix my buttons on top.

body: Column(
  children: <Widget> [
    Container(
      //..... This should be fixed, contained buttons
    ),
    Container(
      // height: 300,
      child: Column(
        children: <Widget> [
          //Image Widget
          Container(
            child: TextField()
          )
        ]
      )
    )
  ])
