FormBuilderTextField initialValue not working when a controller is specified

[awhitford]

For a FormBuilderTextField, I noticed that the initialValue does not seem to be used when I specify a controller. I am seeing a blank text field, rather than the initial value.

This is the default behavior in TextFormField in Flutter. This is because while using a controller you are supposed to specify the value within it.

In fact, there's an assertion in Flutter that doesn't allow you to specify an initialValue when the controller is set.

OK, if this is expected behavior, then that's fine. I didn't see anything documented, and noticed that it wasn't working so wanted to mention it.

Note that I didn't notice an assertion if I specify both for a FormBuilderTextField. Should it?

Use static for your variable etc. For example:

static String myText;
