All Google developers are happy people but she does shine, why? beacause Google is the only company that treat employees as human? You don't have a stupid boss stressing you, you can psuse, take a nap, work with your pet, and exercise you choose the time you feel more productive that make people happy.

Flutter is such a great little technology. I've been using it in production since the alpha and the beta builds have been very stable aside from a few small dart 2 related hiccups. I also started doing flutter videos on my channel and have seen a large amount of interest in learning the technology which is really cool. I personally enjoy making the videos because the language and framework have such a good developer story. I feel that the flutter team really nailed what they set out to do (make a technology that is easy to use without sacrificing power and performance). Dart itself is a powerful but overlooked programming language and I hope that flutter brings up into the spotlight as Dart's "killer app". I've been following and using Dart for at least 5-6 years now (both in production and as a hobby language). I honestly can't tell you how many people I've seen who have been able to pick up Dart in a few hours and then use it to build something tangible.

@ramirodeelias4516 6 лет назад

I still don't understand why they are supporting both kotlin and flutter at the same time with such enthusiasm, and none of these flutter videos tell you exactly the difference between them and why would I use one over the other. Does anybody know?

@abhishekmeher1245 6 лет назад

Flutter is cross platform. If you are interested only in a single platform it might not be of much use to you.

@harvindersingh-xb2pz 6 лет назад

Nothing can replace kotlin/java. Because nothing can beat the speed of native apps. But sometimes you just dont want to manage two code bases and this is where flutter can help if you need to make it available on android and ios

@ardakucukoz8922 6 лет назад

Hello everyone, I hope it is not late to ask questions. I have a few questions about how to implement flutter. I am new in flutter and I made really simple app that has just one list view that shows the items. However, I realized that app size is huge. After compiling, it is 60mb. The same thing in native app is 2 or 3 MB. Is it normal or am I missing something? Another question is, can I create an application for both iOS and Android using flutter that have specific functionality for different platforms? For example, I am trying to add some additional future for Android side, but not for iOS. Is it possible in flutter? Thank you very much for any advance.

@SethLadd 6 лет назад

@SureshKumarMajhi 6 лет назад

Flutter till now not supported any 3D engine. They are fully focused right now on 2D only. Ref - flutter.io/faq/#can-i-build-3d-opengl-apps-with-flutter

@draakisback 6 лет назад

Yeah, I have a tutorial that I am doing on my channel (not on this account) where I am building a minesweeper game with flutter. I've also built a 2048 game in flutter and I've done a few canvas based 3d experiments. You can make highly performent games using flutter, the max fps is like 120 which is very nice for games. That being said the 3d graphics are not that well optimized at the moment mainly because the platform is still in beta. You can cheat out 3d games however by either using platform channels (plug it through android or iOS or both) or just directly in the dart code.

What has been mentioned about Kotlin isn't accurate. Kotlin covers Browser ( kotlinlang.org/docs/reference/js-overview.html ), Server-side ( kotlinlang.org/docs/reference/server-overview.html ; ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-CbL1d2Nd3Rg.html ), Desktop ( kotlinlang.org/docs/reference/faq.html#can-i-use-kotlin-for-desktop-development ), Android ( kotlinlang.org/docs/reference/android-overview.html ), and iOS development ( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3Lqiupxo4CE.html ) through its multi-platform approach ( kotlinlang.org/docs/reference/multiplatform.html ; blog.kotlin-academy.com/architecture-for-multiplatform-development-in-kotlin-cc770f4abdfd ; ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-afc5PUs_EPE.html ) which is the biggest difference between Kotlin and Dart (uses the cross-platform approach just like some other languages like C# and JS) when it comes to developing for multiple platforms. The key points with multi-platform development are the following: - Heavy emphasis on platform integration and the UX - Only business logic is shared (also includes test logic) across multiple platforms (UI isn't shared) - Very high level of platform interop (covers all key things including APIs, tools, UX design, and best practises) that is close to seamless (low maintenance curve with the minimal interop abstraction), and has a very low level of boilerplate/ceremony involved - Can easily keep up with platform changes (very quick turnaround time unlike other cross-platform technologies) One very important thing to note about Kotlin with iOS is that the first professional Kotlin iOS app was approved by Apple with the first App Store submission. It is "very rare" that a iOS app written in a non Apple technology is accepted by Apple without being rejected multiple times.

I teach a Mobile Apps Course and we are using Flutter extensively. Fantastic. And Emily's enthusiasm is absolutely infectious. The series of videos featuring her and the rest of the Flutter team are excellent and my students agree. Emily has a knack for doing much more than just showing you code. She's fantastic at providing a deep conceptual understanding of what is actually going on. She, along with her Dart/Flutter video colleagues, have a way of making complex things simpler, which is precisely what we want to empower young programmers. Awesome!

@bhavikcpatel 6 лет назад

Wow! great to know about Dart and Flutter. Would you mind suggesting best and fast way to learn Dart and Flutter? do you think learning Dart first would help or learning Flutter and Dart together make more sense? just excited to learn Dart and Flutter. (want to see if Flutter is more powerful than ReactNative or not)

@EmilyFortuna 6 лет назад

I am the sort of learn-as-I-do person, so I recommend trying to learn Flutter, and you'll pick up Dart along the way. Dart you'll find is very easy to pick up if you know any sort of C-syntax-style language. You might check out the new UDacity course that got released not too long ago, and send us feedback if you're looking for something different! www.udacity.com/course/build-native-mobile-apps-with-flutter--ud905

On the images used in memes -- a lot of popular memes, like the Unsure Fry knowyourmeme.com/memes/futurama-fry-not-sure-if or the I don't know what I expected Arrested Development gif knowyourmeme.com/memes/i-don-t-know-what-i-expected are all based on creative property made by movie studios (and/or actors if there are live people in the images). They technically own the rights to those images, and could require that Google pay them a bunch of money if we showed them without their consent. "Licensing is Complicated!" (TM) ;-)

How to implement cloud vision API on flutter

@EmilyFortuna 6 лет назад

My understanding of the cloud vision API is that it's just a REST api, so you can still access it by making an http request in your app. There's an example of that in the talk I do here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iflV0D0d1zQ.html (linked to the time spot where I talk about it)

She says flutter => native but why is it slow and big?

@EmilyFortuna 6 лет назад

slow and big how? What are you using to measure?

@VijayKanta 6 лет назад

Ok, so I tried rewriting a native Android app, one page had a scrollview with multiple blocks of two columns of imageviews. This I could only achieve in flutter through a single ListView and each row acting the block. The scroll in native version (scrollview) is full 60fps, where as there's so much of jerkiness in the flutter version. Possibly 15-20fps during scroll.

@EmilyFortuna 6 лет назад

That's very surprising. Do you have your code up anywhere so we can take a look at it to see what's going on? What device are you using?

@karthikl5354 6 лет назад

Can i add tensorflow model in flutter app?

@EmilyFortuna 6 лет назад

Hmm. I don't think we have a plugin to do native tensorflow mobile/lite computations on device yet. Contributions welcome, though!

@karthikl5354 6 лет назад

Then should i go with native android studio apps which supports tensorflow lite?

@EmilyFortuna 6 лет назад

If you want to use tensorflow lite and not implement a plugin for flutter yourself right now, then yes, you'll want to write an Android or iOS the "normal" way. However, since TF people give instructions on how to run these models on both platforms I don't think creating a plugin yourself should be that hard. I'd also ask you to consider why you want to run your deep network locally on your phone (as opposed to running on a server/cloud). There can be good reasons for that, but if you're willing to run your model in the cloud then you can totally do that by just using any old REST request with Flutter (and you can run a more complicated model anyway that way).
