    React Native Navigation

    React Native Navigation

    A complete native navigation solution for React Native

    React Native Navigation is a module, dependent on and intended to be used alongside React Native, so some experience with it and knowledge of core concepts is required. We also assume you are working on a Mac with XCode and Android Studio installed and setup. You can also make it work in a Linux distribution, of course, but in that case bear in mind that some sections of the docs that deal with iOS might not be relevant to you. When your app is launched for the first time, the bundle is parsed and executed. At this point you need to display your UI. To do so, listen to the appLaunched event and call Navigation.setRoot when that event is received. When your app is launched, RN makes sure JS context (which is what enables you to execute JavaScript code) is running. There are quite a few differences between iOS and Android in this regard.

    Flutter InAppWebView Plugin

    Flutter InAppWebView Plugin

    A Flutter plugin that allows you to add an inline webview

    A Flutter plugin that allows you to add an inline WebView, to use a headless WebView, and to open an in-app browser window. Adding the InAppWebView widget into your app is very simple. It’s just a widget like any other Flutter widget. Use InAppBrowser or ChromeSafariBrowser to open an in-app browser! ChromeSafariBrowser is based on Chrome Custom Tabs on Android and on SFSafariViewController on iOS. Create a Class that extends the InAppBrowser/ChromeSafariBrowser Class in order to override the callbacks to manage the browser events. It can be used to run a WebView in background without attaching an InAppWebView to the widget tree. As InAppWebView, it has the same options and events. Use InAppWebViewController to control the headless WebView instance.

    Fomantic-UI

    Fomantic-UI

    Fomantic-UI is the community fork of Semantic-UI

    Fomantic is a development framework that helps create beautiful, responsive layouts using human-friendly HTML. Fomantic UI treats words and classes as exchangeable concepts. Classes use syntax from natural languages like noun/modifier relationships, word order, and plurality to link concepts intuitively. Get the same benefits as BEM or SMACSS, but without the tedium. Fomantic uses simple phrases called behaviors that trigger functionality. Any arbitrary decision in a component is included as a setting that developers can modify. Performance logging lets you track down bottlenecks without digging through stack traces. Fomantic comes equipped with an intuitive inheritance system and high-level theming variables that let you have complete design freedom. Develop your UI once, then deploy with the same code everywhere. The only dogma from this framework: everything arbitrary is mutable.

    Douya Bean sprouts

    Douya Bean sprouts

    A Material Design app for douban.com

    The open source Material Design Douban client. Among all people who directly access Douban, the most common and consistent usage is around ratings, comments, discoveries, and discussions around movies, TV, books, records, and events (what we call "items"). We will use the ratings and comments that are synchronized with the website as a starting point and basis to reconstruct the discovery and discussion around personal interests on the mobile phone. Douban is never a single website, and the usage of Douban is naturally different. Douban is used to obtain information, but whether the acquisition of information is based on entries and algorithms, or based on neighbors and people, this issue has probably remained unresolved in the multiple revisions of Douban. Douban Broadcasting has been one of the few Android Design applications in China a few years ago. Actively express the characteristics of Douban, such as broadcasting, neighbors, Douyou, etc.

    Simple, semantic markup. Supported in all major browsers, horizontal/vertical slide and fade animations. Multiple slider support, Callback API, and more. Hardware accelerated touch swipe support. Custom navigation options, compatible with the latest version of jQuery. Display your products in a neatly designed, responsive slideshow within WooCommerce. FlexSlider was built to serve up the best responsive jQuery slider around. I had built a few implementations of responsive sliders on different client projects and noticed that there was a glaring hole for plugin support with the concept. I wanted to build a plugin that would serve the newest of beginners, while providing seasoned developers a tool they could use with confidence. What has come forth is this, FlexSlider. I plan to maintain this plugin and provide support to users implementing FlexSlider into their sites. Responsive web design can be tricky, but I hope that FlexSlider serves to uncomplicate the process, just a little bit.
