Fair 2.4.0 – New Features, Architecture, Roadmap, and Quick‑Start Guide for the Flutter Dynamic Framework

Fair is a dynamic framework designed for Flutter that enables runtime updates of widget trees and state without requiring a new app release.

Version 2.4.0 adds full null‑safe support, compatibility with Flutter SDK 2.5.x series, and FlatBuffers generation of binary files in a null‑safe environment.

The demo section updates the sample project with modernized demos and adds iOS runtime support.

Recent planning includes the upcoming Fair 2.5.0 release, adaptation to Flutter 2.8.x, addition of a generic JS template, more syntactic sugar, new beginner documentation, an IDE lint plugin, and a Fair technical salon scheduled for late June.

Fair Lab describes a hot‑update platform based on Flutter and a Dart server, aiming to provide a zero‑cost integration of Fair’s hot‑update capabilities, and explores a low‑code online editor for dynamic editing.

Quick integration steps: add the Fair dependency and compiler to pubspec.yaml, configure version overrides, then initialize the app with FairApp.runApplication(...) and embed dynamic components using

FairWidget(name: 'DynamicWidget', path: 'assets/bundle/lib_src_page_dynamic_widget.fair.json', data: {"fairProps": json.encode({})})

.
