    Lieber Johannes, ich mag Deine Stimme, Geschwindigkeit und Dialekt. Die aufbereiteten aktuellen Themen und mini Serien in kleinen Einheiten . Für indischen Dialekt bevorzuge ich 2 andere RUclipsr. Wenn’s das war und Du den Kanal verkauft/vermietet hast, dann Danke für das letzte Jahr - ohne Dich wär ich nicht soweit gekommen!

    Hey i want to have types of users in my application admin/user/staff. How would i implement this using firesbase auth?

    • @mohammadragheb4962
      @mohammadragheb4962 2 года назад

      U got two options
      1- Define a user role in firestore for each user
      2- A better solution is to use custom claims (require cloud function) it’s a bit complicated and advanced but worth the effort

      So the user i define in firestore only needs lets say the email from the fire base auth?

    Hi @JohannesMilke
    Ich hab dich vor ein paar Wochen schon mal gefragt, ob man einen http get request im Hintergrund einer app ausführen kann (obwohl diese geschlossen ist). Du hast zwar gesagt es kommt auf die Todo List, aber bis jetzt hab ich es nicht gefunden. Ich möchte dir keinen Druck oder jegliches bereiten. Ich wollte dich nur freundlich erinnern und fragen, ob und wann das Video ca erscheinen würde.
    LG Martin

    I started learning Flutter and I found your channel, I really appreciate your efforts for bringing so much content, but you have way too much content. Can you guide me on how to best use your channel for learning Flutter. Also is there any path which I should follow on your channel for systematic learning.
    Thanks!!

      This channel isn't really for systematic learning, it's more like a helper channel, assuming you already have some background, then, when you need help with some things, you can find them here

    Hey Johannes, the new instructor is definitely getting better. However, a lot of us still think that a new person should start a new channel. You can always promote his channel from your channel if you want to help him. If you are going to continue down this line, you may loose some of your subscribers.
