About

LocalSend is a cross-platform app that enables secure communication between devices using a REST API and HTTPS encryption. Unlike other messaging apps that rely on external servers, LocalSend doesn't require an internet connection or third-party servers, making it a fast and reliable solution for local communication.

How it Works

LocalSend uses a secure communication protocol that allows devices to communicate with each other using a REST API. All data is sent securely over HTTPS, and the TLS/SSL certificate is generated on the fly on each device, ensuring maximum security.

For more information on the LocalSend Protocol, see the documentation.

Getting Started

To compile LocalSend from source code, follow these steps:

1. Install Flutter.
2. Clone the LocalSend repository.
3. Run cd app to enter the app directory.
4. Run flutter pub get to download dependencies.
5. Run flutter run to start the app.

It's possible that the issue is caused by a mismatch between the required Flutter version and the installed Flutter version.

LocalSend uses fvm to manage the project Flutter version (specified in .fvm/fvm_config.json). After you installed it, run fvm flutter instead of flutter.
