DivKit 🐋 is an open source Server-Driven UI (SDUI) framework. It allows you to roll out server-sourced updates to different app versions. Also, it can be used for fast UI prototyping, allowing you to write a layout once and then ship it anywhere using Flutter. DivKit is an excellent choice to start using server-driven UI in your project because it can be easily integrated as a simple view in any part of your app. At the starting point, you don’t need a server integration. You can include all JSON on the client-side to try it in a real-world application.

Also, we’ve made a sandbox for you to experiment with. You can try different samples in the web editor and see the results. You can use the DivKit website to find a lot of handy samples and documentation, but feel free to ask us anything in the Telegram community chat.

How it works #

DivKit builds native views from JSON data.

JSON → DivData → DivKitView

  • JSON – raw data with templates in DivKit format (see DivKit schema).

  • DivData – data objects parsed from JSON (see Generated DTO).

  • DivKitView — plain Flutter Widget (you use it directly)

Playground app #

Since the Flutter client does not support full-fledged launch on the web, therefore, in order to poke the functionality, you need to run an example of the current library. Use DivKit playground app to look through layout examples and supported functions.

Supported features #

Flutter client is in development, feel free to contribute and help community use DivKit on this platform.

Supported components (may contain unavailable features for more info look at documentation):

  • text
  • image
  • container
  • state
  • input
  • gallery
  • custom

DivKit Flutter. Quick start. #

Build app and draw your first DivKitView. #

  1. Add dependency to pubspec.yaml:

        divkit: any
  2. Import library

    import 'package:divkit/divkit.dart';
  3. Resolve your layout with DivKitData:

    from JSON:

    final data = DefaultDivKitData.fromJson(json); // json is Map<String, dynamic>

    or from card and templates:

    final data = DefaultDivKitData.fromScheme(
        card: json['card'], // Map<String, dynamic>
        templates: json['templates'], // Map<String, dynamic>?

    P.s. The process of building a DTO is quite expensive, so it is better to create it outside the widget in order to avoid frame loss.

  4. Use DivKitView inside your widget tree with layout passed by param "data":

        data: data, // DivKitData

    Please ensure that there is Directionality widget in the tree.

    Optionally, you can pass customs handler, actions handler and other params to configure DivKitView behavior:

       data: data,
       customHandler: MyCustomHandler(), // DivCustomHandler?
       actionHandler: MyCustomActionHandler(), // DivActionHandler?
       variableStorage: MyOwnVariableStorage(), // DivVariableStorage?

    P.s. If you wish to work with default div-actions and use your own actionHandler don't forget to inherit DefaultDivActionHandler.
