Problem

Cannot launch project with macro with Map param.

Macro

import 'dart:async';

import 'package:macros/macros.dart';

macro class MapEntryExample implements ClassDeclarationsMacro {
  final Map<String, String> map;

  const MapEntryExample(this.map);

  @override
  FutureOr<void> buildDeclarationsForClass(
    ClassDeclaration clazz,
    MemberDeclarationBuilder builder,
  ) async {}
}

Example

import 'package:test_macros/map_entry_example/macro.dart';

@MapEntryExample({
  'a': 'b',
  'c': 'd',
})
class Target {}

void main() {
  Target();
}

Output

@MapEntryExample({
