Flutter Keyboard makes textfield hide

 new Scaffold(
      appBar: new AppBar(
          ...
      resizeToAvoidBottomInset: true,
      ....

Fixed problem textfield was hidden by keyboard

This was the case with me . You are definitely wrapping a scaffold inside another scaffold . there should be only one scaffold widget inside your flutter app i.e the main layout . Simple remove all the ancestor scaffolds you have and keep only one scaffold . dont wrap a scaffold into another scaffold .inspite of that you can wrap a scaffold inside a container .

Make sure in your main.dart file you are not doing this :-

✖✖

return Scaffold(
body : YourNewFileName(),
);

Inspite of the above code do this:- ✔✔

return YourNewFileName();

This answer is not specific the question above but may be useful to those who are still having issues with the keyboard covering the selected text field, no matter what they do. I got to this page while trying to resolve such an issue.

Prior to the problem I had been making some changes to try and improve my splash screen on app startup. As per someone's recommendation, I had included the following line in the <resources><style> section of the styles.xml file in the android/app/src/main/res/values folder

<item name="android:windowFullscreen">true</item>

This had the unexpected effect of stopping any fields scrolling up in the main app when the keyboard is displayed. This might be obvious to some, but it wasn't to me.

Hope this info helps someone.

resizeToAvoidBottomPadding is Deprecated use instead resizeToAvoidBottomInset: true
