Sicherstellen, dass in jedem Event eine list von groupIDs zufinden ist.

Das Feld in userMap namens "homeFeed" beinhaltet eine Liste von eventID Strings. _homeFeedMainEventID nimmt das Element 0 der Liste.
Aus diesem Grund muss der Code so geschrieben werden, dass mehrere Events berücksichtigt werden können

Meine Mutter sagt:

• Bei mit Eltern koppeln eher Begriff "verbinden" benutzen. Koppeln sei nicht eher unverständlich.
• Auf der selben Page gibt es Rechtschreibfehler

Folgender Error wird geprintet, wenn man sich als TN anmeldet:

Das App stürzt wenn der ios path für das documen fehlt bzw. ein leerer String mitgegeben wird. Ziel dieses Issues ist, diese empty paths zu finden und zu beheben.

Es fehlt groupID

Nein, das soll so sein!
Eltern "folgen" kinder. Kinder "folgen" gruppen.
Die Eltern bekommen die GroupIDs mit dem Lesen der Kinder mit. Grund dafür: Kinder können Gruppen ändern.
-d

Der Device Token wird zur Zeit nicht in der Firebase abgespeichert. Ursprunglich mal im Home State.
Überdenken von folgendem:

• Speicherort in der Database (unter groups oder im userProfile als Liste?)
• An welcher Programm stelle abfangen, z.B wenn man vom Registrieren in die Root-page weitergeleitet wird.

Der DisplayName sollte ja, wenn ich es richtig verstanden habe, entweder der Pfadiname oder der Vorname (falls kein Pfadiname existiert) sein.
Wollen wir nicht auch einen Eintrag displayname im userMap machen?

Die Cloud Functions sind momentan in us-central. Sie in europa zu deployen könnte die Geschwindigkeit verbessern

Sicherstellen, dass keine devices Leer sein kann.

Der Text der Liste mitnehmen soll nicht bei langem Text unter den Punkt landen.

Am 18.02.2020 jährt sich unsere App entwicklung. Wollen Wir etwas machen?

Text Mitnehmen und Bemerkung werden abgeschnitten

Wie auf der Website eine Leiterliste machen in der App für Teilnehmer und Eltern.

Auf Bildschirmen mit gekrümmten Screens wie das S9 ist die Login-Page und die "Eintrag in Agenda hinzufügen"-Page zu nah am Rand und man kann schlecht den Text lesen. Würde vorschlagen mehr margin einzustellen.

IOS- Version, alle Packages funktionieren ausser:

• cloud_messaging
• Barcodescan (irgend welche in Rechte in der info.plist)

Make it possible to then upgrade the child account to a full account with credentials

Beit TN-Registrierung wird bei Stufenauswahl nach dem Auswählen die GruppenID angezeigt und nicht der Gruppenname.
Geburtstag wird auch noch falsch angezeigt als Monat/Tag/Jahr, anstatt wie wir es sonst in der App haben Tag.Monat.Jahr.

@roranmorea, hasst du push-notifications bereits mit messages implementiert - oder muss dies noch implementiert werden?

Um Users mehreren Gruppen zuteilen, müssten wir groupID zu einer List machen und die Rechte, also kann anschauen, anmelden, bearbeiten in der groupMap verteilen. Ich bin mir nicht sicher ob wir das jetzt implementieren wollen oder erst in v2

Nei muss ahpasst werde

Beim Registrieren eines Elternteils wird nach dem Geburtstag gefragt. Braucht es dies wirklich @roranmorea?

Fehlermeldung mit rotem Bildschrim:

The following assertion was thrown building FutureBuilder<DocumentSnapshot>(dirty, state: _FutureBuilderState<DocumentSnapshot>#d596d):

Either the assertion indicates an error in the framework itself, or we should provide substantially more information in this error message to help you determine and fix the underlying cause.
In either case, please report this assertion by filing a bug on GitHub:

Idee: Wenn man sich in der App registriert wird gleichzeitig auch die E-Mail, Vor-, Nachname und Stufe im Mailchimp E-Mail-Verteiler registriert.
Grund: Ich sehe ein Problem bei unserer Pfadi, dass neue Teilnehmer so viele Accounts machen müssen auf verschiedensten Plattformen: Anmeldung per Papier fürs Midata, Registrierung für den E-Mail-Verteiler auf der Homepage und jetzt käme noch eine Registrierung für den Account für die App dazu.
Wenn es ok für dich ist @Rumpelstilzli, dann würde ich versuchen dies nach meiner Prüfung (21.01.) zu integrieren. Ich habe es bei Mailchimp nachgelesen und denke es ist nicht so schwierig, weil eine gute Dokumentation der API vorhanden ist.

1. Nur Functions write rights
2. Deine Usermap lesen
3. Eltern ihre kinder und umgekehrt
4. Leiter alles lesen

es wird kein Eintrag im UserMap gemacht für die groupID, welche gebraucht wird um initMoreaFire() in der RootPage zu machen.

(0.6.6-dev) [Firestore]: The behavior for java.util.Date objects stored in Firestore is going to change AND YOUR APP MAY BREAK.
W/Firestore( 771): To hide this warning and ensure your app does not break, you need to add the following code to your app before calling any other Cloud Firestore methods:
W/Firestore( 771):
W/Firestore( 771): FirebaseFirestore firestore = FirebaseFirestore.getInstance();
W/Firestore( 771): FirebaseFirestoreSettings settings = new FirebaseFirestoreSettings.Builder()
W/Firestore( 771): .setTimestampsInSnapshotsEnabled(true)
W/Firestore( 771): .build();
W/Firestore( 771): firestore.setFirestoreSettings(settings);
W/Firestore( 771):
W/Firestore( 771): With this change, timestamps stored in Cloud Firestore will be read back as com.google.firebase.Timestamp objects instead of as system java.util.Date objects. So you will also need to update code expecting a java.util.Date to instead expect a Timestamp. For example:
W/Firestore( 771):
W/Firestore( 771): // Old:
W/Firestore( 771): java.util.Date date = snapshot.getDate("created_at");
W/Firestore( 771): // New:
W/Firestore( 771): Timestamp timestamp = snapshot.getTimestamp("created_at");
W/Firestore( 771): java.util.Date date = timestamp.toDate();
W/Firestore( 771):
W/Firestore( 771): Please audit all existing usages of java.util.Date when you enable the new behavior. In a future release, the behavior will be changed to the new behavior, so if you do not follow these steps, YOUR APP MAY BREAK.

• Trigger verbessern
  Push notification wird getriggert, falls event Map geändert wird
• deviceToken aus userMap holen
  Es wird eine neue Methode geschrieben, die aus dem Priviledge Map die devTokens 1. TN , 2. Leiter, 3 Eltern als Array herausgeben kann

Die Agenda Seite wird richtig angezeigt, aber es wird folgender Fehler in der Konsole angezeigt:
