Storybook is an open-source tool for building UI components and pages in isolation. It streamlines UI development, testing, and documentation. Storybook provides a sandbox to build UIs in isolation so you can develop hard-to-reach states and edge cases. Implement components and pages without needing to fuss with data, APIs, or business logic. Render components in key states that are tricky to reproduce in an app. Save use cases as stories in plain JavaScript to revisit during development, testing, and QA. Use addons to customize your workflow, automate testing, and integrate with your favorite tools. Stories are a pragmatic, reproducible way to keep track of UI edge cases. Write stories once then reuse them to power automated tests. Whenever you write a story you get a handy test case. Quickly browse stories to make sure your UI looks right. Pinpoint UI changes down to the pixel by comparing image snapshots of stories. -

Epoxy
Android library for building complex screens in a RecyclerView
Epoxy is an Android library for building complex screens in a RecyclerView. Models are automatically generated from custom views or databinding layouts via annotation processing. These models are then used in an EpoxyController to declare what items to show in the RecyclerView. This abstracts the boilerplate of view holders, diffing items and binding payload changes, item types, item ids, span counts, and more, in order to simplify building screens with multiple view types. Additionally, Epoxy adds support for saving view state and automatic diffing of item changes. We developed Epoxy at Airbnb to simplify the process of working with RecyclerViews, and to add the missing functionality we needed. We now use Epoxy for most of the main screens in our app and it has improved our developer experience greatly. If you are using layout resources in Epoxy annotations then for library projects add Butterknife's gradle plugin to your buildscript. -

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. -

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. -

GiftedChat
The most complete chat UI for React Native
See the files in example-slack-message for an example of how to override the default UI to make something that looks more like Slack, with usernames displayed and all messages on the left. Avatar as user's initials. Localized dates. Multi-line TextInput. InputToolbar avoiding keyboard. Redux support. System message. Quick Reply messages (bot). Typying indicatior react-native-typing-animation. If you decide to specify a text prop, GiftedChat will no longer manage its own internal text state and will defer entirely to your prop. This is great for using a tool like Redux, but there's one extra step you'll need to take, simply implement onInputTextChanged to receive typing events and reset events (e.g. to clear the text onSend). If you are using Create React Native App / Expo, no Android specific installation steps are required, you can skip this section. Otherwise, we recommend modifying your project configuration. -

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.
