isVoid abstract method

Determines whether this method declares a void return type.

This method inspects the method's declared return type and returns true if it is explicitly void. It is useful for AOP frameworks, reflection systems, and code generation tools that need to distinguish between methods that produce values and those that perform side effects only.

Example

class Logger {
  void log(String message) {}
  int countLogs() => 42;
}

final logMethod = Class(Logger).getMethod('log');
final countMethod = Class(Logger).getMethod('countLogs');

print(logMethod.isVoid());   // true
print(countMethod.isVoid()); // false

@return true if the method’s return type is void, false otherwise.
