isar VS flutter_tts

I would have appreciated some more details on the benchmark. SQLite has notoriously slow writes in the default journal mode, but proper configuration and WAL/WAL2 mode should be a starting point for any comparison.

It's the first time I've heard of Isar[1] though. I'm always surprised at how many solid-but-underused Apache projects are out there, chugging along.

I have a few flutter projects that have used Hive and have been fairly happy with it (except for a recent schema change that crashed production...but a story for another time), though will need support for more structured queries for a future project. Isar seemed to fit the ticket: made by same developer, nice API, supports queries, etc, except there is an ongoing discussion raising concerns I share. In short, it is not actively maintained, or at least inconsistently maintained. Isar v4 is on the horizon, but not ready for production, while v3 seems to have some serious bugs. It seems like a great project by a talented developer, but having only a single contributor is a serious risk.

Tracking stuff helps me in being motivated and can be the decision point if I do something or not. I'm sure there are some flaws in the app, so I'll be grateful for every feedback. It's written in Flutter. - [Isar](https://isar.dev/) for database. - [Stacked](https://pub.dev/packages/stacked) for the architecture. - [Syncfusion](https://pub.dev/packages/syncfusion\_flutter\_charts) for the charts. Here are some links, if anyone is interested: [Youtube video link](https://www.youtube.com/watch?v=dgQUU8AmtkY) [Play Store Link](https://play.google.com/store/apps/details?id=com.vinsho.tally\_tracker)

- Isar for database. I tried sqflite and hive but ended up with Isar.

Hive is a good option. Though I would also suggest checking out isar which is really powerfull offline storage db and its quite fast. Its built by the author of Hive himself so its quite reliable. https://isar.dev/

I'd definitely recommend looking at Isar, https://isar.dev/.

For all the rest, you will use the exactly same thing you use in Kotlin. Each Flutter plugin can Java, Kotlin, Swift and Objective-C code to support it. For instance: Text to Speech. If you get this plugin: flutter_tts | Flutter Package (pub.dev) you will notice that it have a Java counterpart ( flutter_tts/FlutterTtsPlugin.java at master · dlutton/flutter_tts (github.com) ) and a lot of swift stuff ( flutter_tts/ios at master · dlutton/flutter_tts (github.com) ) to do the same for iOS. Dart talks to this plugins sending messages (a string for the name of the action (i.e. "speak") and parameters). So, if your "native" Kotlin import will add some startup time or will inflate your app from 4Mb to 30Mb, the same will happen in Flutter.
