GGroup: Firestore.instance.collection("blah").where("something", isEqualTo: stringVariable) doesn't work
If you put an actual string where stringVariable is, then it works fine. But for some reason if that string is in a variable it doesn't work. EG: stream: Firestore.instance.collection("entries").where("sessionId", isEqualTo: "mySessionId").snapshots() works fine. However this: stream:

Reddit: Question about Login With Amazon on Flutter
Hi I'm still learning Flutter and am considering moving an existing app I have as an Android/iOS native app to Flutter. However, this app pairs with an Alexa skill, so for authentication we use Login With Amazon. As far as I can tell, I don't believe there is a way to do this because Amazon does not have a Dart sdk, but I'm still very new at this so I just wanted to make sure before I decide to not convert this app into a Flutter app.I just did a quick check of the rules and believe this is still the best place to ask this question, but if I should be reaching out to the Amazon and/or Flutter team instead of asking here, let me know.Regardless, I'm having an awesome time learning Flutter and can't wait to learn more. Thanks!
