Flutter Startup Time
Hi, I am currently developing my first big flutter app and I don’t know when it started, but at some point the app startup time just was pretty slow with ≈8 seconds on my IPhone.So I just wanted to hear some opinions about that: is that a common issue, are there some ways of improving the startup time or any best practices?Or in a more general sense, is there something you learned about good performing apps that you wished you knew when you started developing with flutter?For example I tried for a long time to integrate a ListView.builder with a few thousand items and with shrinkwrap enabled until I stumbled over a video explaining that shrinkwrapping the listview makes all the items render at once…I searched for days for a solution yet it was so easy to fix..Did you have such learnings as well?

Flutter web - initial loading
hey, flutter web at current state is already amazing, the only annoying part to me is this initial load time (3s to 8s, to start canvaskit or load dart.main.js), do you think this will be possible to fix ever? Given that behind the scenes flutter is a graphic render engine and not an html page that can load instantly.

unknown properties
I am new to the Reactnative and flutter freelancing but I want to ask what do you do if the client asks about a property that you don't know about or anew function that you dont know its logic....I know you search stackoverflow or google it but how you search about something that you dont know about it how you explian your view to the one you ask even you dont know the name of the property its you search about something vague ....how do you face this uncertainty in that carrer ......forgive for my fear and confusion of uncertainty

dependencies in pubspec.yaml
If a package such as flame_rive depends on flame, is there an advantage to also specifying flame in the dependencies. For example, should I do this:yaml dependencies: flutter: sdk: flutter flame_rive: ^1.0.0 flame: ^1.0.0Or, is it okay to delete the line that has flame and just do this:yaml dependencies: flutter: sdk: flutter flame_rive: ^1.0.0I notice that the auto-import of VS Code may not be detecting some of the flame packages when I do CTRL-.

When people say flutter gives you control of every pixel, what does that mean exactly?
Wouldn’t this apply to native development as well or is flutter doing something different? It’s confusing to me since with native development you have the most control over the app.

Another movies app 😅
Hello everyone, since that networking, controllers are components that we always rewrite for each project.I decided to make a small starting point project to show help making development for the next app easier.The app use :Hive as a local database Getx as state management Dio networking library firebase to login/register http mockup adapter to simulate network requestsA video sample here:demo videoSource code can be found here :source codeI would be grateful for any feedback or if anyone have comments about making network requests cleaner or simplifying Controllers/UI connections.

How can I use Tik Tokers in my app?
Dear Flutter CommunityI am currently working on this app. It's about guessing who has more followers. I want to show ads. I know that it is possible because there is an app called TikDance, which is doing something similar and also shows ads. I have already tried reaching out to the creators of TikDance for legal advice but they did not respond. The images get fetched at runtime. I thought that supplying the image source would be enough but I'm really unsure. Does anyone have a good source showing me what i have to write into my app to secure me legally?thx in advance

Enjoy Rust, a modern language with performance, reliability and productivity, seamlessly with Flutter: flutter_rust_bridge comes with more features and elaborated doc
Link: https://github.com/fzyzcjy/flutter_rust_bridgeLast time, flutter_rust_bridge was still a small project with many rough edges, but now it is much better. Not only does it have much more features, but we even have a small "book" discussing the features, tutorials, and configuration steps in detail.A quick overview of the advantages:Memory-safe: Never need to think about malloc/free.Feature-rich: enums with values, platform-optimized Vec, possibly recursive struct, zero-copy big arrays, Stream (iterator) abstraction, error (Result) handling, cancellable tasks, concurrency control, and more. See full features here.Async programming: Rust code will never block the Flutter. Call Rust naturally from Flutter's main isolate (thread).Lightweight: This is not a huge framework that includes everything, so you are free to use your favorite Flutter and Rust libraries.Multi-platform: Android, iOS, Windows, Linux, MacOS (Web coming soon)Easy to code-review & convince yourself: This package simply simulates how humans write boilerplate code. If you want to convince yourself (or your team) that it is safe, there is not much code to look at. No magic at all! (More about safety concerns.)Fast: It is only a thin (though feature-rich) wrapper, without overhead such as protobuf serialization, thus performant. (More benchmarks later)Pure-Dart compatible: Despite the name, this package is 100% compatible with pure Dart.I want to say thanks to all our contributors: Desdaemon, SecondFlight, AlienKevin, surban, Unoqwy, antonok-edm, efc-mw, valeth, trobanga, Michael-F-Bryan, bus710, rustui, and the contributions can be seen in the changelog. Special thanks for Desdaemon, who has been contributing a lot of PRs, such as enum structs, options (nullablity), many bugfixs, and documentation overhaul.P.S. Cross-posted from https://www.reddit.com/r/rust/comments/swrbyv/write_ui_using_flutter_a_crossplatform_hotreload/ since this library relates to both Flutter and Rust

Does anyone know some good flutter sample/open-source projects/repositories that build on very_good_cli?I working on my flutter packages where I need to study some common patterns and standard structure of projects.Since I'm new to very_good_cli so I don't know about its structure and it's also different to find on GitHub.So if anyone knows about some repo so please share I need at least 10 to 15.
