<b>Impressions after switching from Xamarin and developing an app with Flutter</b>
I have background in Xamarin.Forms development (<a href="https://github.com/maxim-saplin/CrossPlatformDiskTest">app1</a> with over 100k installs, <a href="https://github.com/maxim-saplin/xOPS-App">app2</a>). Some time ago while experimenting with <a href="https://www.reddit.com/r/FlutterDev/comments/gztwcu/flutter_performance_considerations_vs_react_and/">Dope Test</a> I got interested in Flutter and decided to give it a try.I've created a <a href="https://github.com/maxim-saplin/dikt">Dictionary app</a> I always missed (used ColorDict before, though was not happy with usability and looks of it).A short summary, <strong>I'm very excited and inspired by Flutter, no comming back to Xamarin and looking forwad to new features and capabilities!</strong>&#8203;<strong>What I liked:</strong>Awesome quick start <a href="https://flutter.dev/docs/get-started/flutter-for/xamarin-forms-devs">docs for Xamarin.Forms devs</a>Way more offten you get what you expect with Flutter than with Xamarin.It's just more stable and predictableI feel like there's more prodiuctivity and less bugs with F&#1076;utterWay fewer occasions of searching for some failures in Xamarin tooling and/or framework (e.g. after VS for Mac or Nuget upgrade, or minor changes to configs/sources in project) that suddenly break smth in the app.Nice YouTube videos explaining widgets and other dev topicsFlutter's framework and plugins complete sources are always local:Easy to step-into and debugOne can easily copy framework/plugin-in code to project directory and change it. Here's what I changed:Flutter's <code>SimpleDialog</code> to allow CustomScrollView inside<code>hive-1.4.1+1</code> to allow non ASCII chars in key value<code>reorderables-0.3.2</code> to implement the scenario of moving an item out of the list and dropping it on 'Delete' areaFirebases's <code>AnalyticsObserver</code> class that can now register ShowDialog navigation eventsLocalization with <code>i18n_extension</code> is more fun than C#/RESX approachHot reload and restart, tinkering with UI is so much faster/easier<a href="https://pub.dev">https://pub.dev</a> is more useful than <a href="https://www.nuget.org">https://www.nuget.org</a> (good search, conveniet integrated docs)Android app size is smallerDecalrative React/JSX style of building the UI is cleaner than XAML + C# code-behindI found Dart very close to C# and easy to start, with me it was faster to grasp rather than KotlinCurious abstraction for integers. There's single <code>int</code> type, there're no <code>byte</code>, <code>long</code> and other kinds of type sizes. Yet there's <code>Uint8List</code> collection type to deal with binray streams.&#8203;<strong>What I didn't like:</strong>Always felt handicapped with ecosystem's philisophy towards multithreading, out of 8 cores on my phone only 1 is effectively available to my code:Isolates model is very limitted. There's no memory sharing, marshaling of only primitive types and collections is available (Dart VM allows marshaling complex objects, not Flutter though)Some framework features and plugin-ins can't be utilized in Isolates:HiveDB can't load different boxes in separate isolates. Although each box is a separate file and there're very few sync issues, there're no quick workarounds that may allow parallel lazy loading of boxes (each in a separate isolate).Loading bundled assets (e.g. <code>rootBundle.loadString(asset)</code> ) in isolates is not possibleThere're several heavy weight scenarious (indexing dictionaries, cold start of app and initializing HiveDB) that could easily be sped up 4-6x times with proper multuthreading<code>StatefulWidget</code> doesn't have <code>build</code> method, due to some (not quite straightforward) implmementation details of Flutter widget tree must be built in <code>State<T></code>MS docs are still better and more complete than Flutter's official…
