Chat/Messaging App Light and Dark Theme
Flutter UI project for building a messaging app interface
Chat Messaging App Light and Dark Theme is a Flutter UI project for building a messaging app interface with both light and dark modes. It includes multiple screens that cover the core visual flow of a chat application, starting with a welcome screen and moving into authentication and conversation views. The project is intended as a design and implementation reference rather than a complete messaging backend. It demonstrates how Flutter layouts can be structured for chat lists, message screens, onboarding, sign-in, and sign-up experiences. The dual theme support makes it useful for learning how to design consistent interfaces across different visual modes. It is best suited for Flutter learners and mobile developers who need a clean UI base for chat-style apps. -

ChatSecure is a free and open source messaging app that features OMEMO encryption and OTR encryption over XMPP. You can connect to your existing Google accounts or create new accounts on public XMPP servers (including via Tor), or even connect to your own server for extra security.

ChatSecure only uses well-known open-source cryptographic libraries to keep your conversations private. Other apps may make claims about "military grade" security but, without publicly auditable source code and verifiable end-to-end encryption, you cannot be truly safe. -

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. -

Interactable
Experimental implementation of high performance interactable views
This is an experimental implementation of a declarative API for handling fluid user interactions with views at 60 FPS in React Native. Here are some example use-cases for views that users can interact with. Swipeable card (a la Google Now) springing into place unless swiped away with enough force. Drawer snapping between closed and open with buttons appearing gradually as it's being dragged. Collapsible header that snaps to a smaller size as the content below is being scrolled. Chat heads (a la Facebook Messenger) that can be dragged around but snap to corners of the screen. All of these use-cases have views that continuously interact with the user's gestures. These interactions are normally physical in nature, having properties like springiness, friction, elasticity and damping. In order to feel natural on a touch device they need to run at 60 FPS. -
