    Welcome to the sweet side of @FlutterDev E2E testing. Introducing Honey 🍯. We @clickup were unhappy with the existing E2E testing solutions and developed HoneyTalk, a test language that is very easy to learn and runs right in your Flutter app.

    We built this entire app in Flutter. Fully native hotkeys, a floating window, deep OS integration, real time AI speech to text etc. Usually designs and marketing material looks a lot cooler than the final product. Not in this case. Flutter allows us to build pixel perfect across

    It is very helpful to see your database content during @FlutterDev development. Isar Inspector even allows you to run complex queries and edit properties in real time.

    Dear Hive Community, I'd like to apologize for my lack of support and updates for Hive over the past year. Despite this, your commitment to the community has ensured that the package is still in a remarkably good state, and for that, I'm incredibly grateful. As many of you

    I'm a little concerned that most of the #flutter tweets I saw recently are about Dart backend, game engines, command line tools etc. All are cool developments but there are so many important issues to solve with Flutter's core functionality: mobile apps.

    Got inspired by @remi_rousselet's great #fluttervikings talk to implement a fully offline pub.dev client in #flutter powered by Isar. It supports offline searching, changing versions, viewing readme files etc. When the user is back online, packages are refreshed.

    Introducing Crimson: A blazing fast JSON parser that is able to parse any Dart object in a single big loop. Preliminary benchmarks using 25MB Twitter API JSON: For full parsing, Crimson is about 3x faster than json_serializable. For partial parsing about 10x. More info soon 😉

    Which state management solution does ClickUp use in the #flutter app? All of them of course! (well, the most popular ones at least) We modularized the app into about 60 packages and depending on the task we choose the right tool 🔧

    I have been working on embedded object and enum support in #isar for the past few months and it is finally ready. Embedded objects can be deeply nested and every property can be used in queries. Enums allow custom database representations and support indexing. #flutter #database

    An Isar user reported a really difficult bug and provided a project to reproduce it. I was able to find and fix the bug within minutes. Thanks so much to all the people who go the extra mile and provide a sample project. It makes all the difference 💜
