AbiSpecificInteger class base

The supertype of all Abi-specific integer types.

Abi-specific integers should extend this class and annotate it with AbiSpecificIntegerMapping to declare the integer size and signedness for Abi.values.

For example:

/// The C `uintptr_t` type. /// /// The [UintPtr] type is a native type, and should not be constructed in /// Dart code. /// It occurs only in native type signatures and as annotation on [Struct] /// and [Union] fields. @AbiSpecificIntegerMapping({ Abi.androidArm: Uint32(), Abi.androidArm64: Uint64(), Abi.androidIA32: Uint32(), Abi.androidX64: Uint64(), Abi.androidRiscv64: Uint64(), Abi.fuchsiaArm64: Uint64(), Abi.fuchsiaX64: Uint64(), Abi.fuchsiaRiscv64: Uint64(), Abi.iosArm: Uint32(), Abi.iosArm64: Uint64(), Abi.linuxArm: Uint32(), Abi.linuxArm64: Uint64(), Abi.linuxIA32: Uint32(), Abi.linuxX64: Uint64(), Abi.linuxRiscv32: Uint32(), Abi.linuxRiscv64: Uint64(), Abi.macosArm64: Uint64(), Abi.macosX64: Uint64(), Abi.windowsIA32: Uint32(), Abi.windowsX64: Uint64(), }) final class UintPtr extends AbiSpecificInteger { const UintPtr(); }
