What steps will reproduce the problem?
Run the follow code in the 64bit linux Dart VM.

import 'dart:mirrors';
 
class Todo {
    final String owner;
    final String task;
    final String dueDate;
 
    const Todo([this.owner, this.task, this.dueDate]);
}
 
checkTodos() {
    reflect(main).function.metadata.forEach((meta) {
        var owner = meta.reflectee.owner;
        var task = meta.reflectee.task;
        var dueDate = DateTime.parse(meta.reflectee.dueDate);
        if (dueDate.compareTo(new DateTime.now()) < 0) {
            throw "$task is not done yet. Blame $owner.";
        }
    });
}
 
get todo => const Todo();
 
// @­Todo('austincummings', 'This this this', '2020-01-01')
@todo
void main() {
    checkTodos();
}

What is the expected output? What do you see instead?
It should give a syntax error or prevent the program from running due to the annotation not being a constant on line 25.

What version of the product are you using? On what operating system?
64-bit DartVM 1.3.6, Linux 64-bit in VirtualBox

Please provide any additional information below.
When running dartanalyzer on the above code, an error is found that reads:

[error] Annotation can be only constant variable or constant constructor invocation (/home/austin/workspace/ddb/test/expando_test.dart, line 25, col 1)
