Flutter Layout Cheat Sheet
Do you need simple layout samples for Flutter? I present you my set of Flutter layout code snippets. I will keep it short, sweet and simple with loads of visual examples. Still, it is work in progress — the catalogue of samples will grow. I will focus more on the usage of Flutter widgets rather than showcasing the components (Flutter Gallery is great for that!). If you have an issue with “layoutin

Android開発におけるモジュール分割
You can't perform that action at this time. You signed in with another tab or window. You signed out in another tab or… モジュール分割とは本題に入る前にモジュール分割とは何を指していて、どういう利点があるのかを整理しておきます。 Androidアプリプロジェクトを新規作成すると自動的にAppモジュールが作成されますが、このAppモジュールを複数のモジュールに分割することが可能で、マルチモジュールプロジェクトと呼ばれることもあります。 Androidアプリ開発においてモジュールは複数の意味をもっていますが、本記事ではLibrary Moduleを指します。 Application ModuleLibrary ModuleDynamic Feature ModuleDagge
Suspending over Views — Example
The Android view system loves callbacks; like really loves callbacks. To give you an idea, there are currently 80+… Let’s take what we learnt in the previous post and apply it to a real-world app use case. The problemHere we have the TV show details UI from the Tivi sample app. As well as information about the show, it lists the show’s seasons and episodes. When the user clicks one of the episodes
The Obvious UI is Often the Best UI
Illustration by Thanh Tran, UX DesignerVoltaire said, “le sens commun est fort rare”—common sense is very rare. Perhaps to realize that a certain decision is common sense, one has to have enough life experience to know the right path to take , at which point certain choices become common sense and don’t require much analysis. When we talk about common sense with product design, what we now see as
エンジニアのコーチング by Kent Beck
以下は、Kent Beckによる「Coaching Engineers」の翻訳です。本人の許可を得て掲載します。tl;dr 有償でエンジニアのコーチをします。詳細と待ち時間についてはお問い合わせください。 物語の結末2018年2月にFacebookを退職する直前に、トップ1%のエンジニア（現在および過去にレベルE7以上だったエンジニア）のオフサイトミーティングに参加しました。海辺のリゾートでバスを降りると、私がコーチをしていた生徒が複数いることに気づきました。そのうち何人かは昇進したことを知っていましたが、その他の生徒には驚かされました。 私にとって、胸がはちきれるほどの誇り高き瞬間でした。私は、生徒たちと関係を築き、彼らの成功のために心の底から尽力してきました。多くの生徒らが成功を収めたことを目の当たりにして、私は大いに驚き、嬉しくなりました。物語はさらに続きます。 Facebookの上
Dependency injection in a multi module project
Let me quickly recap what Plaid looks like from a bird’s eye view. We have an app module, which contains the main launcher activity. Also there are several dynamic feature modules (DFM) which depend on the app module. Each DFM contains at least one activity, code and resources related to only the feature in question. The app module depends on a core module which contains shared code and resources

Animating on a Schedule
I was recently part of a great team working on the Google I/O 2018 Android app. This is a conference companion app, allowing attendees and remote folks to find sessions, build a personalized schedule and reserve seats at the venue (if you’re lucky enough to be there!). We built a number of interesting animated features in the app that I believe greatly enhanced the experience. The code for this ap
Google I/O 2018 app — Architecture and Testing
The Google I/O app is an open source project which shows the schedule and information for the annual Google I/O conference. It is aimed at attendees and remote viewers of the event.
