VxEnsureVisibleWhenFocused class

Helper class that ensures a Widget is visible when it has the focus For example, for a TextFormField when the keyboard is displayed

How to use it:

In the class that implements the Form, Instantiate a FocusNode FocusNode _focusNode = new FocusNode();

In the build(BuildContext context), wrap the TextFormField as follows:

new VxEnsureVisibleWhenFocused( focusNode: _focusNode, child: new TextFormField( ... focusNode: _focusNode, ), ),

Initial source code written by Collin Jackson & taken from one of his repo. Extended (see highlighting) to cover the case when the keyboard is dismissed and the user clicks the TextFormField/TextField which still has the focus.
