origami 0.0.2

Origami is a Server-Driven UI (SDUI) library for Flutter that allow to build beautiful cross-platform applications with JSON in real time.

Origami

Origami is a Flutter library for building server-driven UIs. It allows you to define UI components and their configurations using JSON, enabling dynamic UI updates without requiring code changes.

Use Case

Sometimes as Mobile Developers, we are required to deliver applications as soo as possible. Moreover, UI changes can occur every week. But if there is a bug or you are asked to modify the UIs, you need to publish the updated app to the app store. This requires time and costs. We need to build flexible pages. So we define a light UI protocol, and implement it on Android and iOS. We can dynamically update App UIs by pushing a json file. With this capability, we can do some UI A/B testing without publishing App to app store. With this project, you can build your UIs from a json string, which is the UI protocol. The json string is very similar to the Flutter widget dart code. All widget types and widget properties are the same.

Installation

To use Origami in your Flutter project, follow these steps:

1. Install the Origami library to your pubspec.yaml file:

flutter pub add origami

Example

Here's a simple example of using Origami to build a server-driven UI.
