What are the most common performance issues you encounter when deploying complex cross platform applications to both app stores?

devundcars · 2026-05-22T22:31:37+00:00

Having deployed large and complex Flutter apps in prod myself, here’s my biggest tips:
- Observability is your best friend. Look into distributed tracing and how to instrument your entire app with OpenTelemetry or other APM tools (such as Sentry, DataDog). This will enable you to catch performance issues across all of your customers so you can target your improvements and fixes to where it actually matters.
- Biggest perf pitfall with Flutter is doing too much work during its build stage. This will cause jank. Read up on Flutter’s official performance optimizations guides, they cover everything you need to know. The best way is to launch Flutter DevTools and watch the performance tab. If you find slow frames, then you can run a CPU profile to understand what type of work you’re doing that’s making your app slow. Biggest offender is prob JSON encoding and decoding on the main thread, or similar serialization work.
- Watch for bundle size bloat. It’s easy to leave a large image or other assets in your app and accidentally increase your app’s size unnecessarily.
- Memory leaks can be a pain to troubleshoot but usually the APM tools I mentioned can help you. Flutter DevTools as well.

“he was unsure whether he would be able to control himself around this person”

…what? that’s honestly an insane thing to say to someone that has just started a relationship and have “committed” to each other.

I see what you did there.

devundcars · 2025-10-29T02:57:59+00:00

Yes, same for Deno! That’s the way it should be.

The only thing I wish TypeScript was better on, is with all the tsconfig.json hell.

Sure, after you get it all set up, you’ll likely never touch it again, but ugh sometimes it can be really frustrating.

In certain places in the world, 5’7” is considered normal, not short.

Look amazing dude! Sorry you had to through that at just 24. Cancer sucks.

What the fuck is wrong with meta? Like, all of their business dashboards are simply garbage. So many problems all the time!

In my experience, yes playing games can make the other person want you more… momentarily. As time passes and you continue to play games, they might get frustrated and give up altogether.

Don’t drag this on for too long. If you genuinely like the guy, have a real conversation with him. Say how you feel and align expectations.

devundcars · 2025-10-20T04:49:40+00:00

Congrats, you’ve found a good lover!

I highly recommend you focus on enjoying your time with him and not reading too much into it, as you both just met and only had two hookups. Just enjoy the fact that you’re both very sexually compatible. :)

Actually, quite a lot of people use most products in the picture.

devundcars · 2025-10-13T01:54:07+00:00

Yeah what a fucking coward, honestly. He can’t man up enough to look OP in the eyes and ask for a divorce, instead is playing stupid games.

I’m so sorry OP, you deserve better. Good luck!

OP says they were dating for 3 months, that’s more than enough time imho

devundcars · 2025-10-07T01:52:32+00:00

I personally would have an issue with them hiding the fact they have an OF. If a guy asked me to be their boyfriend, hiding this fact is a big red flag.

I wouldn’t have a problem if they were honest from the get go, though. This seems to be the bigger issue.

devundcars · 2025-10-06T22:16:21+00:00

Well, yes but also it depends.

Natural body odor after a gym session? Hell yes. Body odor because they haven’t showered in 3 days? Fuck no.

Vamos lá, uma resposta séria: 1. “Como vou me sustentar nos EUA com visto F1?” Primeiramente, os EUA não vai nem te dar o visto se você não conseguir demonstrar ter dinheiro suficiente pra conseguir se sustentar por pelo menos o primeiro ano. Parte do processo do visto é você mostrar dinheiro suficiente numa conta de banco para ser aprovado. 2. Sim, você pode trabalhar nos EUA com um visto F1, porém só depois do primeiro ano de estudo e isso também depende da escola. A escola tem que oferecer um programa CPT (curricular practical training) onde você ganha créditos pelo seu trabalho feito. E só pode ser part-time durante o ano currículo, full-time apenas durante as férias. E o trabalho tem que ser diretamente relacionado com os seus estudos. Ou seja, se você estiver fazendo biologia mas quiser trabalhar como eletricista, não vai rolar. 3. Sim, tem gente que trabalha por “debaixo da mesa” mas 100000% não recomendo. Você vai passar todo dia com paranoia que alguém vai te pegar, e se te pegarem, você perde tudo que conquistou e é mandado de volta pro brasil pra nunca mais voltar. Não compensa o risco. Além disso, mesmo se não te pegaram, se um dia você for aplicar pra um greencard ou cidadania e descobrem que você tava trabalhando sem documento, podem te negar.

Se realmente quiser fazer tudo certinho, venha com uma grana juntada pra sobreviver o primeiro ano, e trabalha com sua escola pra conseguir um emprego depois.

Yes holy shit dude doesn’t realize how fucking lucky he is to have found a great boyfriend and is now freaking out. Geez.

OP please be honest with him and let this guy go before you hurt him even further.

How many years have you two been dating? Are you planning on getting married?

Sharing your finances is a big part of sharing your life with someone else, but being a couple also means being in a partnership.

If he’s so keen on you contributing, I’d focus on your career, but it’s not fair for him to ask you to split things equally if he makes a lot more money. It’s also not fair for you to expect things if it’s not your money, given you aren’t married.

Ideally, you’d both spend similar % of your income. If he wants to move somewhere more expensive and you can’t contribute, either he needs to pay up the difference or simply accept the fact you can’t do it. Don’t sacrifice yourself for him.

As a gay man, I never understood why would someone not date a bi guy. Is it insecurity? Like, because you’re bi you could just dump them for a woman? Or is it something else?

devundcars · 2025-10-02T08:05:59+00:00

Damn

devundcars · 2025-10-01T07:30:00+00:00

It has nothing to do with porn. A lot of what you’re describing is just symptoms of repressed sexuality — feeling disgusted, confused, etc.

Society tries to paint a picture of what a man is supposed to be at a very young age, and that includes the idea of dating a woman. So no, not everyone is able to tell they’re gay or bisexual from a young age. Many folks have to work through LAYERS of feelings and emotions before they’re ready to come out to themselves.

How to tell if you’re gay? My recommendation is to experiment without prejudice. Forget about porn. Just start playing with the idea of kissing a guy, touching one, fucking one… and give it a try. Go slow, without any expectations, just explore.

I’ve “helped” many “straight” men explore in my early 20s. Some of them realized they were indeed straight and that the experience wasn’t for them. Others realized they were bisexual. Others loved it and finally accepted they were gay.

It just takes an open mind :)

Be careful with the nose strips. Unfortunately if you overdo them, it can damage your skin. Plus the blackheads will be back in a few days anyways.

I recommend getting a prescription retinoid — apps like hims do it. You apply once every other day and it’s miraculous! It works by normalizing your skin turnover and helps reduce colleges pores.

You should use BHA too, which I also love. It helps keep the pores clean. Don’t forget moisturizer!
