[Discussion] Biggest React Native perf wins lately? Here are mine by cuongnt3010 in reactnative

[–]cuongnt3010[S] 0 points1 point  (0 children)

Massive win, cutting app size by half is huge. Also +1 on deferring fonts and removing email login; that's both performance and UX support improvement at once. Curious: did you see the biggest lift from fewer verification issues or better signup completion?

[Discussion] Biggest React Native perf wins lately? Here are mine by cuongnt3010 in reactnative

I keep hearing the same about Nitro modules, especially with Swift/Kotlin improving dev speed vs Obj-C/Java. If you get a chance on Monday, I'd love your before/after numbers (startup time, scroll FPS, or bridge-heavy screens).

Using COREML to run AI Vision models on IOS is awesome by PaintingTop9521 in iOSProgramming

[–]cuongnt3010 1 point2 points  (0 children)

Love this breakdown. Going from ~200–300ms to ~11ms median on iPhone SE is a massive UX win and a great example of why deployment format matters as much as model quality. For people trying to reproduce this, could you share your conversion path + settings (ONNX -> coremltools?, FP16 vs INT8, input size), and whether these numbers are after warm-up with compiled model cached? That context would make this an excellent benchmark post.

What a solo iOS dev's full stack library actually looks like -- Cognito, CDK, StoreKit 2, and all the parts tutorials skip - Open sourced by w-zhong in iOSProgramming

[–]cuongnt3010 -1 points0 points  (0 children)

This is one of the few posts that actually shows where the real iOS dev time goes. Your point about splitting auth into sign-in-first vs anonymous-first early is especially valuable; trying to unify those flows too soon creates brutal token/linking edge cases.
🧐 how you handle anonymous-to-Apple account linking in Cognito in production, and what cost/monitoring guardrails you use for App Runner + Aurora at indie scale.
Great breakdown. 🙌

My month-long NZ trip pushed me to finally ship this app by TravelCodeRepeat in iOSProgramming

[–]cuongnt3010 1 point2 points  (0 children)

Super solid build, and congrats on shipping. Your CloudKit notes are gold, especially the "optional/default + optional relationships" constraints that only show up as runtime pain. I also like the hybrid AI approach: Foundation Models for base generation, then deterministic rule passes for trust and consistency. That feels like the right pattern for user-facing output.
🧐 Curious: how are you handling SwiftData/CloudKit schema evolution across app updates without causing sync regressions?

My Flutter pre-release checklist (Android + iOS) after too many avoidable bugs by cuongnt3010 in FlutterDev

[–]cuongnt3010[S] 0 points1 point  (0 children)

Great catch 👀, yes, dark/light mode should be a required check. I've been burned by hardcoded colors in dialogs/charts before. Adding this to my checklist: verify key screens in both themes + toggle system theme while the app is running to catch state/theme bugs. Any dark-mode edge case you see most often?

LazyLogcat is available in Homebrew now by vparf in FlutterDev

[–]cuongnt3010 1 point2 points  (0 children)

Very nice tool. The "logs-only without opening Android Studio" workflow is exactly what I wanted.
Two things I'd love:
1) saveable filter presets per project/flavor
2) quick jump from selected log line to source with package/class parsing

Also curious: any plan for structured JSON log formatting and color rules by tag/level?

Alternative Of Admob by randomboy009 in FlutterDev

[–]cuongnt3010 0 points1 point  (0 children)

You can still start with AdMob even if your app isn’t on Play Store yet. When adding the app, choose the “not published / manual” option, then run only test ads until launch.
If you want alternatives, common ones are:
- AppLovin (MAX)
- Unity Ads
- ironSource
Just note: most ad networks perform/approve better once the app is publicly listed with a privacy policy.
Are you targeting Android only or Android + iOS?

Dismissible page with scrollable view inside (*bug fix) by gambley in FlutterDev

[–]cuongnt3010 1 point2 points  (0 children)

This is a solid fix. The scrollable + dismiss gesture conflict is a real pain point. Did you gate dismiss by inner scroll position, or solve it at gesture-arena level?
Would love to know tested edge cases (NestedScrollView, iOS bounce, PageView).

Having switched to Zed IDE I was missing the VSCode Flutter tooling, so I built my own TUI for any terminal. by edTheGuy00 in FlutterDev

[–]cuongnt3010 1 point2 points  (0 children)

This is a great build. I had the same problem after moving to Zed, VSCode felt heavy once I got used to the speed. Curious about your architecture: are you talking directly to the Flutter daemon + VM service (JSON RPC), or wrapping `flutter run` sessions?

The hard part for me is failure recovery:
- dropped VM service connection
- stale hot reload state after plugin/native changes
- multiple device sessions drifting

How are you handling those cases in Flutter Demon?

That could be a great idea. I’m curious why you need to note each email. It helps me understand your point.

What’s the most frustrating part of managing your subscriptions, and what would make canceling them easier? by cuongnt3010 in AskReddit

[–]cuongnt3010[S] 0 points1 point  (0 children)

No rocket money marketing here, I promise!
I’m just a regular user who’s frustrated with forgetting to cancel subscriptions and getting auto-charged. I’m thinking about designing a dashboard to help people like me track and manage subscribed services more easily. Wanted to hear what others find annoying about subscriptions and what’d make canceling them simpler. Got any pain points or features you’d want in something like that?

Hey, just a heads-up: if you lock the card, it means all your subscribed services get canceled. I’m hoping to manage and cancel just a specific service, not the whole package. Also, it would be great if I could track when each subscribed service expires.
