…to android_dev

Usability Update

New features:

• Login / Register page submit button debounce
• Set user avatar on profile page
• Send pictures and gifs
• Pending contacts in contact list ( contacts that you'd sent a request to )
• Requesting contacts in contact list ( contacts that had sent you a request )
• Better appearance on search page
• Constraint only one window instance at a time

Bug fix:

• Prevent users from adding themselves as a contact

Known issues:

• Avatar glitches in contact page
• Close chat page when sending a message/file cause unexpected result
• Right shift crashes the app ( seems like a bug of flutter's )

Planned features:

• Unread message notification dot
• Push message
• Android/iOS platform package
• Pre-offered stickers ( maybe capoo )

Important to know:

• The installer.exe is packed by inno, and does no harm to your computer, it'll clean itself up when you uninstall it
• The packed exe is dedicated to host at 127.0.0.1, for other host address, you might need to compile from the source code

Bug Fix

Add directories & sqlite.dll in inno setup file.
