hasTeam method

bool hasTeam(
  1. String teamId
)

Whether the team claim includes teamId.

Teams are pure grouping: belonging to one grants nothing on its own, so this is for the application's own gating, never an authority check.

Implementation

bool hasTeam(String teamId) {
  if (teamId.isEmpty) return false;
  return teams?.contains(teamId) ?? false;
}
