2-way @bind-Value on bool IonToggle and IonCheckbox don't compile

[Dan Gould]

Maybe this is because Value is set to type bool? instead of bool

Yes, there is an example of ion toggle in the dark mode preferences page in chaincase. It is a nullable bool and the type must match for the event callback to match. The reasoning behind it is that a checkbox can have 3 states: checked, unchecked and indeterminate

This issue remains. I get that there's a way to 2-way bind but @bind-Value doesn't work. ion-checkbox's value attribute and checked attibutes are type bool in javascript. indeterminate is another field entirely. I'm not telling you anything new there.

You're right. I was overthinking this since I was reading the Ionic source instead of the docs which had the value marked as a nullable type. IonToggle and IonCheckbox will now use a bool instead of bool? in the 1.0.7 release
