Personally I favor Flutter for its rapid development speed and feature richness. (I wrote >300k lines of code Flutter app, deployed in both mobile Android/iOS and desktop Windows/MacOS/Linux)
Flutter can communicate with Rust conveniently via https://github.com/fzyzcjy/flutter_rust_bridge/ (Disclaimer: I wrote that library, originally for my personal use)
Not sure about your case, but for my own case it is very similar and I reused almost all code. If you are talking about different UI, flutter's widgets are like React widgets, and you can freely write some conditional branches to combine widgets differently on desktop and mobile. |

I was using Tauri before and it was nice, as I know web technologies pretty well, but my app used to send a lot of images to Tauri from Rust and it was pretty slow. I changed from Tauri callbacks to using web-server inside rust app and run Tauri just to display this webapp, which still used some Tauri exposed JavaScript APIs and it was faster but still slow for 1000 images that were loaded in the list. See more on Tauri discord. I decided to port my app to flutter, but as I am learning flutter at the same time I am progressing slowly. In that time I have also authored commits and opened bugs at flutter_rust_bridge. Will report when I will have rough numbers for same scenario using flutter and flutter_rust_bridge. |

Interesting observation! Personally I feel it smooth. By the way, Flutter 3.0 is released just a few days ago with improvements especially on desktop. Not sure whether it has improvements on performance. Anyway I feel both Flutter and Tauri are excellent :) |

Sadly, Tauri has poor ipc, which is very important for us, we can not afford sacrificing performace by choosing Tauri. I do not think Tauri can solve this problem in short term because it highly depends on underlying webview. |

In addition to the very positive comments for both approaches, what you will also find in the Tauri community, is that people there are very accessible and helpful. Not only does the core team gladly review and accept PRs - we also actively adopt upstream projects in order to maintain them so that Tauri and the broader open-source community can continue growing. But again, both are solid choices. Maybe the things that resonated the most, are:

I have an entire set of blog articles on Tauri, Flutter and other cross platform technology bases starting here https://fluentreports.com/blog/?p=1288 -- however for those who don't want to read an entire book. 😀
If your only two choices are Flutter and Tauri, imho, Flutter is the significantly (& I seriously mean significantly) safer choice, even though I'm personally not a big fan of Flutter. As much as I don't like Electron apps, Electron is also a much better choice than Tauri because the Browser is the exact same fixed engine version for all platforms, which then eliminates a entire class of web compatibility complexity that Tauri has... |

As for different engines problem, TypeScript can be compiled to specific version of JavaScript and if I remember correctly it was observed that minimum JavaScript version across Tauri platforms is ECMA2018. But I did encounter that some things were working in Linux but not on Windows so targeting specific JavaScript version isn't complete solution, but definitely part of it. |

There is also actual differences between the JS in JSCore and V8, some features work, and some features act a bit differently. For example things like this were broken the last time I check in JSCore, but worked fine in v8. |

under what kind of use case? AFAIK, Tauri does not embed node.js so the memory usage should be much smaller in general. |
Beta Was this translation helpful? Give feedback.

See the blog, it answers most the questions but in summry:
The hello world app, Tauri is quite a bit smaller as long as you don't isolate it using AppImage (snap, flatpak, etc) where certain shared memory is no longer shared. But in a much more detailed app with multiple images -- Tauri is actually within spitting distance of Electron even as a stand alone (non-appimage, using fully system memory 100% shared) app. See the attached table from by blog...

I don't disagree, there is a reason I don't recommend Flutter normally. ;-) But when you are limiting it to only Flutter vs Tauri, it is an easy choice imho based on my experience with both platforms... |

Fyi, the up-to-date issue for "caret forcing a redraw" is flutter/flutter#33939 and it's already fixed for Android and iOS and was specifically called out in the Flutter 3 announcement blog. Seems likely to be fixed on desktop within a month or two. |

Since you’re already using flutter for mobile, does it not make sense to evaluate that stack on desktop? If (and I know it’s a big if) it works out, having the common stack on both will really help regarding development speed and ability for community to contribute to all platforms ? |

Both are good but Flutter seems to be better in my opinion since it natively compiles on every platform and Flutter/Dart is growing. I always prefer if apps that are design for multiple devices to be written in Flutter. |
Beta Was this translation helpful? Give feedback.
-
|
You know that natively compiles doesn't mean anything right? Dart AOT is slower than its JIT mode and being slow is not a virtue. As for the flutter SDK and tauri/electron/ionic they are all written in the same language: C++. |
Beta Was this translation helpful? Give feedback.
-
|
@LifeIsStrange Dart AOT was slower than it's JIT mode years ago, but it's long since surpassed it (at least in the vast majority of cases). And JIT is not allowed on iOS so it's definitely good that Flutter doesn't use it. |

In a similar discussion with a dev team, someone brought the fact that with Tauri you can use webgl whereas in Flutter the opengl support is very poor. We have the need to also target mobile platforms for the interface of our new project. Does someone has experience with multi-platform development requiring opengl ? At some point in our discussion with the dev team someone also suggested to develop inside Unity or another game engine supporting multi-platforms. |

My understanding is with Flutter OpenGL/Vulkan/Metal support is actually very good, since that is actually how the engine works all the time (Everything is driven via the native graphics sub-system). There are even a couple Game engine projects written in Flutter/Dart. But I haven't personally tried calling opengl directly myself, but you might want to try it out before dismissing it. As for using Unity (very buggy) or Unreal (very heavy), I have used them. 😀 Actually currently investigating Sciter and a couple other not quite as mainstream mobile/desktop engines... ;-) I'll have to look into Tauri's mobile stuff, but I suspect it will be very much like Ionic/PhoneGap/Cordova with the same pro's and con's if it is the same binding to native browser system as they do on the Desktop.... |

I haven't worked with Flutter, and I'm currently studying React and Tauri. I'm interested in working with Rastdesk, so I wanted to implement this. I noticed that many people are interested in implementing on Tauri, so maybe it will be useful to someone. Of course, development on Tauri and React should not interfere with development on Flutter |

Yes, the development is at an early stage. My main focus is the backend development and I am familiar with react. Сurrent task is to reproduce frontend calls to Rust through Tauri commands |

Though our open source mobile side is Flutter, but I can not decide either. Our desktop side uses Sciter, similar to html/js. We can use most of old html/js with Tauri. We can also reuse some mobile Flutter code, but our desktop design is super different from mobile. Flutter is not css based, few code can be shared between mobile and desktop per my understanding.
Drawback of flutter:
Debugging rust with Flutter is not conveninent.
Both of them are open source, but Tauri has much smaller code base, we can do code change on Tauri, but it is hard for us on Flutter.
Our final choice is Flutter
