How to programmatically make keyboard textfield open

Question

Hi I was wondering if it was possible in flutter to programatically open up the keyboard as well as have the cursor and the textfield ready type straight away.

I already know how to pull up the keyboard FocusScope.of(context).requestFocus(FocusNode());

But I also need to know how to make the textfield ready to type without the users having to tap the textfield. as in

Lets say I have a textfield:

TextField(
  controller: textEditingController,
);

I would like to use code to the effect below so that the user dons't have to tap the textfield

textEditingController.openTextField()//Pseudo code

: Edit -----------------------------------

Bit bad of me but I forgot to add the focus node as a parameter on the textfield

Within your class add

final FocusNode _focusNode = FocusNode();

then add to textfield

TextField(
  ...
  focusNode:_focusNode,
  ...
);

then call it by running

_focusNode.requestFocus();

First, you need to define FocusNode variable and assign it to your TextField like this :

//in header class
FocusNode focusNode  = FocusNode ();

//in build method
TextField(focusNode: focusNode,)

Then use this code:

FocusScope.of(context).requestFocus(focusNode);
