How to add space between keyboard and focused TextField in flutter? - flutter

Question

I have this problem with scrolling, when I focus the text field the red container covers the Textfield, where i want to write.
How can I control the scrolling, so that the Textfield shows above the red container?
I want to show the red Container above the keabord, and when the user writes in the Textfield I want to activate the nect button.

FocusNode _focusNode = new FocusNode();

body: Stack(

Expanded(

I could give you an idea. Try something like this,
body: Column(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Container(
height: MediaQuery.of(context).size.height * 0.9 - 60,
child: Row( ..... ), // Include SingleChildScrollView too
),
Container(
padding: EdgeInsets.only(left: 10.0, right: 10.0),
height: 60,
child: Row( ... )
)
]
Hope that solves your issue.
