Photon

Photon is a cross-platform file-transfer application. It uses http to transfer files between devices.You can transfer files between devices that run Photon. No wifi router is required, you can use hotspot.

Features include e.g.:

• Cross-platform support: For instance you can transfer files between Android and Windows
• Transfer multiple files:You can pick any number of files.
• Pick files faster: Most of the apps use file_picker for picking the files. But for android it caches files before retrieving the paths. If the file size is large it will result in considerable amount of delay. So I have tweaked file_picker to avoid caching(android) unless it is required (some files need to be cached). No matter how many files are selected ,paths will be retrieved within no time. (Note:Caching issue is android specific)
• Smooth UI: Material You design.
• Works between the devices connected via mobile-hotspot / between the devices connected to same router (same local area network)
• Uses cryptographically secure secret code generation for authentication (internally): Even though the files are streamed at local area network,files cannot be downloaded/received without using Photon. No external client like browser can get the files using url,as secret code is associated with url. It will be regenerated for every session.
• Supports high-speed data transfer: Photon is capable of transferring files at a very high rate but it depends upon the wifi bandwidth. (No internet connection required)
