    Popcorn Time for iOS

    Popcorn Time for iOS

    https://github.com/PopcornTimeTV/PopcornTimeTV

    PopcornTimeTV was an Apple TV, iPhone and iPad application to torrent movies and tv shows for streaming. Since 2016, this project has grown exponentially - both in its user base and in its functionality. However, the team size has gone the other way. We went from having 13+ developers on the team to 1 developer and 1 designer, both of whom have lives and projects outside of Popcorn Time. We have decided that we have given our all to this project and it's time for us to move on to pursue greater things. There is no doubt that this comes with a heavy heart as we have learned so much from this project and watched it grow from this simple torrenting app that could only play 720p video, to what it is today. All that being said, we do not want this project to just die after we leave. The size of the project might be a bit daunting to an unseasoned developer but the app is extremely stable and packed with almost every feature you could need.

    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.

    Infinite Scroll

    Infinite Scroll

    Automatically add next page

    Infinite Scroll is a JavaScript plugin that automatically adds the next page, saving users from a full page load. You’ve likely seen it in use all over the web. The original version of Infinite Scroll was first released by Paul Irish 2008. It was a break-through work of front-end development, granting web developers a cutting edge experience via a user-friendly yet powerful jQuery plugin. That lineage scrolls on to this day. Infinite Scroll v4 supports Chrome 60+, Edge 79+, Firefox 55+, Safari 11+. For IE10 and Android 4 support, try Infinite Scroll v3. Infinite Scroll upholds URLs by changing them automatically as the user scrolls. Users can refresh the current page or return to a scrolled page and their position will be maintained. No more tears when you scroll 20 pages and accidentally hit refresh. Try out the full page demo.

Create buttons that support Glyph icons, and are themeable using Bootstrap Brands. BootstrapButtonGroup Allows BootstrapButtons to be grouped together and their attributes controlled en masse. BootstrapProgressBar Displays progress in a bar from 0-100, and animates updates to the current progress.

    Litho

    Litho

    A declarative framework for building efficient UIs on Android

    Litho uses a declarative API to define UI components. You simply describe the layout for your UI based on a set of immutable inputs and the framework takes care of the rest. With code generation, Litho can perform optimisations for your UI under the hood, while keeping your code simple and easy to maintain. Litho can measure and layout your UI ahead of time without blocking the UI thread. By decoupling its layout system from the traditional Android View system, Litho can drop the UI thread constraint imposed by Android. Litho uses Yoga for layout and automatically reduces the number of ViewGroups that your UI contains. This, in addition to Litho's text optimizations, allows for much smaller view hierarchies and improves both memory and scroll performance.
