InterfaceType is not a subtype of Class in VariableGet

flutter dart types build

I have updated the flutter version to 1.20.2, and I have not encountered any problems, knowing that I use JsonSerializable as well, try this:

Remove these files:

pubspec.lock
.packages
.flutter-plugins
.flutter-plugins-dependencies

then apply flutter pub get command

flutter dart types build

First, you have to remove the following files from your code:

pubspec.lock

.packages

.flutter-plugins

.flutter-plugins-dependencies

and then you have to apply the flutter pub get command.

flutter dart types build

supported data types of json_serializer are:

string.
number.
boolean.
null.
object.
array.

so please reflector your data class
