In this episode, Laurence Moroney (@lmoroney) meets with Emily Fortuna (@bouncingsheep) from the Dart Team at Google to talk about her role as a Chief Meme Officer, as well as a software engineer working on the Dart Language. They geek out over Flutter, and how it can change your mobile development for the better! Oh, and you might even get to hear Laurence sing a little bit of Hamilton...

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.

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!

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.

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 ; kzfaq.info/get/bejne/ech8ZMdjs8qXgps.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 ( kzfaq.info/get/bejne/abKhnNih3dWYc3k.html ) through its multi-platform approach ( kotlinlang.org/docs/reference/multiplatform.html ; blog.kotlin-academy.com/architecture-for-multiplatform-development-in-kotlin-cc770f4abdfd ; kzfaq.info/get/bejne/l8yTaLOG2MWpgHk.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 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

How to implement cloud vision API on flutter

@EmilyFortuna 6 жыл бұрын

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: kzfaq.info/get/bejne/n8yciZN1lcqVqoU.html (linked to the time spot where I talk about it)

@VijayKanta 6 жыл бұрын

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 жыл бұрын

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).
