i got aqueduct 3.2.1 and tried to have many to many relation but got error, so i thought thats maybe its my fault. Then i copied code from documentation:

class Team extends ManagedObject<_Team> implements _Team {
  @Serialize(input: false, output: true)
  List<Player> players;
}
class _Team {
  @primaryKey
  int id;

  String name;

  ManagedSet<TeamPlayer> teamPlayers;
}

// This type is a join table
class TeamPlayer extends ManagedObject<_TeamPlayer> implements _TeamPlayer {}
class _TeamPlayer {
  @primaryKey
  int id;  

  @Relate(#teamPlayers)
  Team team;

  @Relate(#teamPlayers)
  Player player;
}

class Player extends ManagedObject<_Player> implements _Player {}
class _Player {
  @primaryKey
  int id;

  String name;

  ManagedSet<TeamPlayer> teamPlayers;
}

and got this error:

You need to specify the type parameter for ManagedSet. They are both ManagedSet<TeamPlayer> teamPlayers.

the relation is work fine, but its crashed after added this lines:

@serialize(input: false, output: true)
List players;

so how to fix it?

if you mean to change List -> ManagedSet, i did:

class Team extends ManagedObject<_Team> implements _Team {
  @Serialize(input: false, output: true)
  ManagedSet<Player> players;
}
class _Team {
  @primaryKey
  int id;

  String name;

  ManagedSet<TeamPlayer> teamPlayers;
}

// This type is a join table
class TeamPlayer extends ManagedObject<_TeamPlayer> implements _TeamPlayer {}
class _TeamPlayer {
  @primaryKey
  int id;  

  @Relate(#teamPlayers)
  Team team;

  @Relate(#teamPlayers)
  Player player;
}

class Player extends ManagedObject<_Player> implements _Player {}
class _Player {
  @primaryKey
  int id;

  String name;

  ManagedSet<TeamPlayer> teamPlayers;
}

The Slack channel (http://slackaqueductsignup.herokuapp.com/) is better for diagnosing user errors than GitHub issues. There are two issues you have.

  1. You are not providing the type arguments to your ManagedSet - if you re-read the example, you missed them.

  2. You are not providing an appropriate type for the transient property (players). There is an error in the documentation here that needs to be fixed. Will resolve this issue and post back here when resolved.
