New post on Flutter Dev Google group: Firestore error after null safety migration My application is working fine before null safety migration. Afterwards I get a runtime error when attempting to read a record, "Error: [cloud_firestore/unknown] Expected a value of type '((Object?) => Object)?', but got one of type '(Object) => Object?'" I thought maybe I did something wrong in March 05, 2021 at 04:02AM by John Boudreaux https://ift.tt/3sWITRL

New post on /r/flutterdev subreddit: WebRTC - the right choice? I have know some Python and JS and recently Flutter caught my eye and I like the approach.Currently I am working on a fun project with a friend and we want to develop an app that also provides the option to have videocalls. Is this possible in Flutter, maybe with WebRTC? Are there good libraries for that or should I stick with React native? March 04, 2021 at 11:26PM by -newme https://ift.tt/3sPZGpj

New post on /r/flutterdev subreddit: Flutter 2 web scrolling performance I noticed some people mentioned an issue with the Flutter 2 web scrolling performance. That's why I made a scrolling demo to check this out. I implemented a similar webpage in Flutter and in plain HTML.Flutter: http://flutter-scrolling-cats.web.app/HTML: https://flutter-scrolling-cats.web.app/plainhtml.html​The demo shows 1000 blue boxes, each with an image (from a set of 6 random cat images, clipped borders, dropshadow) and a text on the right side. When you click on the image, it animates its height to a new random height.Notice: On mobile the layout isn't the best. Put your phone into landscape to better test scrolling while clicking on images.​My observations:Scrolling performance is great on both implementations (M1 mac, Chrome) as well as mobile (Pixel 4, Chrome)On my Pixel 4 the text re-layouting is slightly more sluggish on HTML while the height animates after a clickFlutter initial loading time is longer for the first time (due to load WASM engine) but as fast as HTML on any further load (PWA caching)When switching tabs Flutter sometimes loses the ability to scroll with left-mouse-click-touch-like-scrolling.​Maybe you can try this out and report your observations, so we get an idea what Flutter 2 web scrolling performance is about.

New post on /r/flutterdev subreddit: Been working on an app using flutter 1.22.6, how should I handle upgrading to flutter 2? Hey everyone. I've been messing with flutter since November 2020 and I read the flutter 2 announcement earlier today.My app isn't super complicated, but it does make use of firebase auth/core, permissions, provider, geolocator, xmpp sdk, dio, localizations, etc. I ran the `outdated` command and I see basically a couple dozen out of date dependencies.What are some best practices for upgrading my dependencies so that I can safely upgrade from v1.22.6 to v2?Also, since I'm still actively developing on this app is it fine to stick with current versions (and also flutter at 1.22.6) for another month or two while the dependencies catch up?Thanks March 04, 2021 at 07:37PM by EquivalentAnalysis66 https://ift.tt/3rhum2D

New post on /r/flutterdev subreddit: I used AWS Amplify for Flutter. My views. To share your experiences, please comment below. I used Amplify Authentication and DataStore for a week to build some prototypes and experienced the following:- Auth: Functionally it worked without any issues, but the authentication process was slow compared to Firebase Auth.- DataStore: Every update made to the data is versioned and when a change is made on the Cloud via AppSync GraphQL API, technically (as per the documentation) the edge device store should get synced upon DataStore initialization on app launch. But, this syncing experienced some amount of background delay (I did not miss adding await) which led to the usage of stale data on device. The local store was updated eventually using the synced data, but this behaviour was not expected in the first-place. March 04, 2021 at 07:43PM by ankmahato https://ift.tt/2Pz5XHM

New post on /r/flutterdev subreddit: Does Flutter Web Endanger The App Stores? As I was watching the flutter announcements yesterday, I got a little scared.Flutter web enables us to create web apps in such a way that circumventing the App Store is profoundly easy for the developer.All it takes is 3-4 influencer apps to pull from the App Store and train people on how to install as a web app and human behavior is transformed from using the App Stores entirely.Then google and Apple have no control over the revenue from their app stores. So is google creating a monster that they will be tempted to destroy? March 04, 2021 at 03:45PM by jbryanh https://ift.tt/38cLYVQ
