abi_specific_integer_mapping_missing
Classes extending 'AbiSpecificInteger' must have exactly one 'AbiSpecificIntegerMapping' annotation specifying the mapping from ABI to a 'NativeType' integer with a fixed size.
Description
#The analyzer produces this diagnostic when a class that extends AbiSpecificInteger
doesn't have an AbiSpecificIntegerMapping
annotation.
Example
#The following code produces this diagnostic because there's no AbiSpecificIntegerMapping
annotation on the class C
:
import 'dart:ffi';
final class C extends AbiSpecificInteger {
const C();
}
Common fixes
#Add an AbiSpecificIntegerMapping
annotation to the class:
import 'dart:ffi';
@AbiSpecificIntegerMapping({Abi.macosX64 : Int8()})
final class C extends AbiSpecificInteger {
const C();
}
