Framework assertion failure with InputDecoration.hideDivider = true when doing hot reload #12261
Description
Steps to Reproduce
I am trying to hide the underline in a text field by doing something like this:
commentTextField = new TextField(
controller: new TextEditingController(),
maxLines: 10,
onChanged: _onDetailsChanged,
decoration: new InputDecoration(
hintText: "Tell us more...",
hideDivider: true,
),
);
When doing a hot reload I get the exception listed below in the logs.
NOTE: This only appears to happen when hot reloading.
