    1. 请勿在调试模式和热重载功能开启的情况下做性能测试。 截止目前文档所示内容,你的应用应该运行在调试 (debug) 模式中,这个模式意味着在更大的性能开销下实现了更快速的开发效率,比如热重载功能的启用,因此你可能要面临较差质量的动画效果。当你准备分析应用性能或要打包发布的时候,你可能需要 Flutter 的 profile 或者 release 构建,相关文档,请查阅文档: Flutter 的构建模式选择。

    1. 情景:单独下载了 Dart SDK

      执行: where/where.exe flutter dart

      出现提示 Flutter SDK 内的 dart 命令不在首位。

      则需要更新 PATH,将 C:\path-to-flutter-sdk\bin 放在 C:\path-to-dart-sdk\bin\ 前面(当前场景)。 重启命令行使修改生效,再次运行 where,此时来自相同目录的 flutter 和 dart 已经排在前面。

    1. Doctor summary (to see all details, run flutter doctor -v): [✓] Flutter (Channel dev, 1.26.0-17.1.pre, on Linux, locale en_GB.UTF-8) [✓] Android toolchain - develop for Android devices (Android SDK version 30.0.3) [✓] Chrome - develop for the web [✓] Linux toolchain - develop for Linux desktop [✓] Android Studio [✓] Connected device (2 available) • No issues found!

      What happened with Ubuntu 20.04 at this point:

      $ flutter doctor Downloading package sky_engine... 839ms Downloading flutter_patched_sdk tools... 1,504ms Downloading flutter_patched_sdk_product tools... 1,469ms Downloading linux-x64 tools... 9.9s Downloading linux-x64/font-subset tools... 666ms Doctor summary (to see all details, run flutter doctor -v): [✓] Flutter (Channel dev, 2.6.0-11.0.pre, on Ubuntu 20.04.3 LTS 5.4.0-81-generic, locale en_GB.UTF-8) [!] Android toolchain - develop for Android devices (Android SDK version 31.0.0) ✗ cmdline-tools component is missing Run path/to/sdkmanager --install "cmdline-tools;latest" See https://developer.android.com/studio/command-line for more details. ✗ Android license status unknown.

      The solution for me was to go to Android Studio, fins SDK Manager whuch was under oprions in the right hand pane and install COmmand Line Tools from SDK Manager. I was then able to fix the licences issue too.

    1. Recently, cross-platform apps have gained more popularity and preference for their native-like experience and low-cost development. As a result, Flutter Vs. Kotlin has become a famous debate.

      Flutter & Kotlin are cross-platform SDKs that allow you to create native-like mobile applications with only one codebase. In simple words, by single coding, you can have an app for iOS and Android.

    1. It's super promising for web apps, just maybe not for web pages. I went from React to Svelte to Flutter for my current app project, and every step felt like a major upgrade.Flutter provides the best developer experience bar none, and I think it also has the potential to provide the best user experience. But probably only for PWAs, which users are likely to install anyway. Or other self-contained experiences, like Facebook games. It does have some Flash vibes, but is far more suitable for proper app development than Flash ever was while still feeling more like a normal website to the average user. It won't be the right choice for everything, but I believe it will be for a lot of things.
    2. Really? I've been using Flutter for about a week and Svelte seems an order of magnitude better designed. I find Flutter overly complicated.
    3. I also find that a lot of the complexity of Flutter can be avoided, and I mostly use it to define the UI as a more app-centric alternative to HTML/CSS.

      I mostly use it to define the UI as a more app-centric alternative to HTML/CSS.

    4. Svelte by itself is great, but doing a complete PWA (with service workers, etc) that runs and scales on multiple devices with high quality app-like UI controls quickly gets complex. Flutter just provides much better tooling for that out of the box IMO. You are not molding a website into an app, you are just building an app. If I was building a relatively simple web app that is only meant to run on the web, then I might still prefer Svelte in some cases.
    5. Others have already said how Flutter renders inside a canvas and how it's difficult/impossible for it to interact with other JS libraries (and why would you want to... the whole thing is so different that even the issues are solved by completely different libraries).
    6. I'm not familiar with Svelte. But the UI itself is handled in a custom canvas on mobile (and probably Desktop?) Though, on the web, it is HTML and CSS.
    7. Unfortunately it is not just the semantic that is broken. There are lot of things.For example if you look at some of the examples (https://flutter.github.io/samples/#/) - you can see that indeed there are some div and p tags but it is not entirely normal DOM elements. For example you can't even select text anywhere on the screen. And there are more and more little things like that.Just to be clear - Flutter for web is great, I'm happy it exists, but it is not comparable to React/Vue or Svelte.IMO Flutter for web is good to post live examples of Flutter code or maybe some last-minute-boss-request to make a web version of existing app, but for not for full-blown web app. :)
    1. Dart Web enables running Dart code on web platforms powered by JavaScript. With Dart Web, you compile Dart code to JavaScript code, which in turn runs in a browser
    1. Provider even includes its own BuildContext sub class, which is why we can work with Provider so seamlessly in the widget tree

      (As a Flutter noob,) I don't follow this implication. Why does having a BuildContext subclass mean that Provider behaves seamlessly in a widget tree? It would be able to extract data from BuildContext parameters passed to it, and pass that information to widgets nested in it without having a customized BuildContext subclass, wouldn't it (or is this besides the point)?

    1. With Flutter, the quality of app development is such that although being a Hybrid framework, the feel is of a native app. Flutter is the brainchild of Google. Companies want to build the best app for the most number of people that they can reach. Flutter fulfills the exact requirements for the developers as well as the business owners.

      There are several factors to consider in the app development like the benefits of Flutter-based app development, the cost to make a Flutter app, etc. The best mobile app designs and development process goes hand in hand with Flutter.

    1. Lack of third-party libraries
    2. follows the reactive development architecture, but with a twist. The main thing to know about reactive programming is that it updates UI contents automatically when you update the variables in the code
    3. open source technology for creating native Android and iOS apps with a single codebase
    1. the relative differences in apk size would likely be smaller with larger apps. Flutter's overhead size is fixed
    1. They are both trying to extract common parts above platform, but Kotlin Multiplatform is interested in logic extraction when Flutter is interested in view definitions extraction. They concentrate on the opposite, and they might highly benefit from working together

    1. with many a flirt and flutter,

      Copy and paste as one line http://ir.uiowa.edu/cgi/viewcontent.cgi?article=1832&context=etd<br> We are often startled by close, sudden, and unexpected encounters with birds when they fly away from their hidings spots. In a fraction of a second, the feeling is like the heart fluttering in rhythm with their wings as our minds try to contemplate where the bird is going next. This may be due to most birds having higher metabolisms that humans, as second to us might be like 20 seconds to them. Readers might not start to feel such sensory effects that Poe intended until they reach the purposefully capitalized "R" of the symbolic Raven as the bird figuratively flies over Poe's head and human senses and into his bed chamber, mind, and poem. Walt Whitman also uses similar bird mannerisms to produce heightening sensory effects in "A Word Out of the Sea": ...."From such, as now they start, the scene revisiting, As a flock, twittering, rising, or overhead passing, Borne hither—ere all eludes me, hurriedly,".... "every day the he-bird, to and fro, near at hand"...."Over the hoarse surging of the sea, Or flitting from brier to brier by day, I saw, I heard at intervals, the remaining one, the he-bird" .... "O night! do I not see my love fluttering out there among the breakers?" Both authors are moved enough to "speak" to the birds which symbolize their both authors' states of despair and mourning. Adam Cunliffe Bradford touches on this in his book, "Communities of death: Walt Whitman, Edgar Allan Poe, and the nineteenth-century American culture of mourning and memorializing", "Whitman’s songs, spurred to life by the mockingbird’s aria and sung in response to it, necessarily weaves the previous melodic elements of both of these songs into his own transcendent aria" Bradford, Adam Cunliffe. "Communities of death: Walt Whitman, Edgar Allan Poe, and the nineteenth-century American culture of mourning and memorializing." PhD (Doctor of Philosophy) thesis, University of Iowa, 2010. http://ir.uiowa.edu/etd/647. **
