On Phoenix I sent this:

APP.Endpoint.broadcast!("room:chat", "new:msg",  %{user: "SYSTEM", body: "PING"})

I was able to fix this by updating:

bool isMember(
      String topicParam, String event, Map payload, String joinRefParam) {

to

bool isMember(
      String topicParam, String event, Map payload, String? joinRefParam) {

I am fairly new to Dart so I am not sure if there was maybe some missing Null safety implementation?

[Quantum-Sicarius]

@macoshita any input on this maybe?

[macoshita]

I'm sorry, thank you for the report.
Maybe this should be done,

bool isMember( String topicParam, String event, Map payload, [String joinRefParam]) {

I will make a PR as soon as possible.

[macoshita]

@Quantum-Sicarius I fixed it in this PR, so you can try it if you like.

[Quantum-Sicarius]

Awesome! Thanks for all your effort @macoshita and @mfeckie!
