Online Conference

1:1 real-time video calling with Flutter + Amazon Chime

A Flutter, Android-first 1:1 video app: host creates a meeting, guest joins with an invite code. Built with GitHub Spec Kit. Signed APK and demo video included.

Dart
GitHub

Abstract

Online_Conference is a Flutter, Android-first 1:1 real-time video calling app on Amazon Chime SDK. A host creates a meeting; a guest joins with a shared invite code. The entire delivery used GitHub Spec Kit.

Problem

1:1 calling samples are either vendor UI kits or incomplete WebRTC demos. Teams need a spec-driven reference that includes invite codes, connection state, and a releasable APK.

Solution

A focused host/guest flow on Chime, specified and implemented through Spec Kit, with a signed release APK and a two-device demo video.

Architecture

  • Flutter client, Android-first.
  • Amazon Chime SDK for media and meeting control.
  • Host creates meeting; guest joins via invite code.
  • Spec Kit artifacts under specs/001-video-calling.

Capabilities

  • Create meeting as host; join as guest with invite code.
  • Local + remote video and two-way audio.
  • Mic/camera toggle, camera switch, leave.
  • Signed APK and end-to-end demo video.

Audience

Teams evaluating Chime for agent/client calling, and anyone studying Spec-Driven Development on a real media app.

Outcomes

  • A runnable Android artifact, not only source.
  • A complete Spec Kit trail from constitution to implementation.
