special thanks to this repo. which I have used as a base to start developing my chat app. https://github.com/VNAPNIC/flutter_nearby_connections
This chat application is a mobile app. that is developed using flutter/dart to allow devices(android/iPhone) to connect with each other using the nearby connection in an offline mode by advertising and browsing, once the connection is established, users start to make a conversion with each other by sending text messages then disconnect after they finish.
You can find more Info in detailed about how is working https://developers.google.com/nearby/connections/overview
- Regarding to android, you need real devices for testing, unlike IOS can be done using simulators.
- Dont forget to enable nearby which will by default turn on (wifi,bluetooth and location) before start.
- This is the first version that contains the basic features of chat like sending a text message, not attachments or audio voice, It can be improved later on.
