I am using platform channel to communicate flutter and native.
From Android Native, I am passing HashMap<String, String>
At flutter, side expecting Map<String, dynamic>
but I am getting the error
Unhandled Exception: type '_InternalLinkedHashMap<dynamic, dynamic>' is not a subtype of type 'Map<String, dynamic>'
if I change Map<dynamic, dynamic> it works, but I want Map<String, dynamic> how to handle this.
