Throws class final

Annotation that declares a function, method, or getter may throw one or more exceptions at runtime.

This annotation is intended to be enforced by the annotations analyzer plugin, which provides the handle_throwing_invocations lint rule.

Usage:

@Throws({FormatException})
void parseData(String input) {
  // may throw FormatException
}

@Throws({MyDomainError, StateError})
Future<void> processData() async {
  // may throw MyDomainError or StateError
}

Note: This annotation does not change runtime semantics. It is purely a static analysis hint to help developers handle potential exceptions.

When a function annotated with @Throws is called, the analyzer plugin will warn if the call is not wrapped in an appropriate try-catch block or otherwise handled.
