问题 I am trying to save an image of a canvas to my firebase database. But when I try to save it I get the following error. Uncaught Error: Reference.set failed: First argument has a key path longer than 768 bytes (6829) Is there any way I can make this string shorter so I could submit it. Below is the code I use to convert it to URL function saveFunction(){ var canvas = document.getElementById("sheet"); var dataURL = canvas.toDataURL(); console.log(dataURL); firebase.database().ref('Cords/' +

Thank you and best

问题 I am using the Realtime Database and Functions for my Flutter app. I've set up local emulators for both Database and Functions, so I can test Functions locally without the deployment cost. Now I want to connect my Flutter app to these local emulators, but I am having some trouble finding out how to do it. The FlutterFire docs describes how to do this for Firestore (https://firebase.flutter.dev/docs/firestore/usage#emulator-usage), but not for the Realtime Database. Surely there must be a way

问题 I am trying to sort a list of User Objects by the order in which User IDs appear in the MessageList Array. The MessageList consists of ID's of people a user is chatting with (ordered by time - using sortwith), which is then to be sent to a User Adapter as a list of Users in the same order as the message list. This is so that username, profile image and other details can be displayed... I have learnt a datasnapshot of the Users from firebase provides as is order and hence needs to be ordered
