Flutter: Equatable props getter with optional parameter
577
The base Equatable.props
getter is declared to return a List<Object?>
, not List<Object>
. Fixing your override to match would allow you to store null
.

I have an object that extends Equatable and contains optional parameters. If I try to add that parameter into the props getter, I get an error
The element type 'String?' can't be assigned to the list type 'Object'
. However, not adding it would imply equality within objects that have a different value or no value in that parameter.class Company extends Equatable { final String name; final String? logo; .... @override List<Object> get props { return [ name, logo, //error here ....
What would the appropriate solution be?

Jacobo Koenig almost 3 yearsAmazing, thanks. I was generating the override with the VSCode quick fix which outputs it without the ?
