PreventNullToAbsent class

Prevents null values from being converted to absent values in generated code for body.

@PreventNullToAbsent()
@POST("/post")
Future<String> example(@Field('foo') String? foo);

Here, if foo is null, the generated code will not convert it to absent. It'll send null as the value of foo.

It is useful when you want to send null as the value to the server. Such as, when you want to delete a field's value from the database.
