After "when" how to update TextEditingContoller

[dyardy]

Thank you for your contributions.

I do have a question that I am searching for an answer to. I was searching for a solution within your public repos' and could not see one.

Within my widget, as shown below, how do I update the initial value of the TextFormField after gettingPost from my ref.watch?

 return ref.watch(getLocalPostProvider(widget.id!)).when( 
      data: (item) => Scaffold(
      ... 
            TextFormField(
                  controller: descriptionController, //<<<<
                  maxLines: 10,
                  minLines: 5,
                  textInputAction: TextInputAction.done,
                  textCapitalization: TextCapitalization.sentences,
                  decoration: const InputDecoration(
                    labelText: "Description",
                  ),
                  onChanged: (v) =>{}
                ),
      ...
      )

I am reviewing the edit_profile_screen.dart page when a id is passed in then you are performing ref.watch(getUserDataProvider(widget.uid)).when ... I want to do this but then set the initial value of the textfield controllers within the when syntax. It seems that this is not possible?

Your assistance is very much appreciated.
