Hive v1.2.0 supports relationships, inheritance and more.
I just published a new version of Hive (key value database for Flutter) and wanted to show you how relationships work:

class Person extends HiveObject { String name; HiveList<Person> friends; Person(this.name); } void main() { var persons = Hive.box<Person>('persons'); var mario = Person('Mario'); var luna = Person('Luna'); var alex = Person('Alex'); persons.addAll([mario, luna, alex]); mario.friends = HiveList(persons); // Create a HiveList mario.friends.addAll([luna, alex]); // Add Luna and Alex to Mario's friends mario.save(); // Persist the changes print(mario.friends); // [Luna, Alex] luna.delete(); // Remove Luna from Hive print(mario.friends); // [Alex] (HiveList updates automatically) } 

You can also find this example in the documentation.The new version also allows abstract HiveObjects and supports inheritance between HiveObjects.

Shifting career to CS
Hello wonderful people, I got here asking for an advice from people who work in the industry rn, so as a beginner I only know java now and I just started android/java tutorial by google on Udacity a couple weeks ago and I don't wanna waste time on just android learning Java and then learning Kotlin as it's google's main language now which is a long process, and i wanna do mobile Dev, i asked some people who work in the field and in the market right now and they highly recommend Dart/flutter as they told me it's the future for mobile dev and soon web and desktop, so as a beginner just started in the field and only know java and basic android dev with java, should i just go with Flutter right away right now and master it and don't waste my time with Java android then Kotlin, or keep doing what I am doing with android/java to get some experience and after i do some apps with java move to Dart/flutter?if you're wondering what my goal is, so my goal is landing a job as soon as possible and do some freelance, so time is a main factor for me cause i quit my job to shift my career

Flutter Web for production
Hi guys. Is there an expected date for Flutter Web to be production ready? I'm starting a project now that should be deployed by June 2020 ish. Should I invest in Flutter? Or won't it be production ready by then? For now the only major problem I see are the load times... I don't care about SEO and I don't need distinct URLs for different pages either, Flutter would fit like a glove.Thanks in advance!

cli tool to update dart imports.
As a user of visual code, refactoring source files (moving/renaming) is a pain as visual code doesn't update import statements.To solve this problem, until vscode provides a fix, I've built a cli tool that is able to move/rename dart libraries and will update any import statements so they point to the new path.You need to install the package globally so run:pub global activate drtimportYou can then move a single dart library or an entire folder by running:drtimport move lib/myfile.dart lib/src/myfile.dartordrtimport move lib/scripts lib/src/scriptsIf you have already moved the file and your imports are screwed you can run the patch commanddrtimport patch scripts src/scriptsThis will find all import and export statements which contain the string 'scripts' and change it to 'scr/scripts'.Check the readme for details on using the app.I strongly recommend committing your code into git before running drtimport.We use it on a mid size project and it works nicely.https://pub.dev/packages/drtimportI hope you find it useful.

Flutter Pro Tip: Prefer Discrete GPU For Smoother Testing FPS
If you are on MacOS running the iOS simulator for testing, and your Mac has a discrete GPU, you can choose to prefer that GPU. It will significantly increase frames per second. My 2018 MBP with Vega 16 discrete graphics was defaulting to the integrated Intel graphics. The frame rate was choppy and slow even on a basic app with just the default material transitions. Switching to discrete feels more like how it does on a real device (even an iPhone SE is smoother than the integrated GPU). A much nicer experience.With Simulator Open: File -> GPU Selection -> Prefer Discrete GPU
