Update our media send flow to allow users to send multiple images/videos
at once. This change includes:
- New in-app media picker flow.
- Ability to caption images and videos.
- Image editing tools are made more prominent in the flow.
- Some fixes to the image editing tools.
Previously, we'd only show the attachment button when the user had
yet to enter any text. To add an attachment after text was entered,
you'd have to go to the three-dot menu. Now we just show a little
attach button in the text area.
I also took the opportunity to clean up other button paddings and
stuff in the compose area so things look better and react to text
sizes more predictably.
A variety of improvements to the image editor, such as:
- New, fullscreen styling
- Smoother lines
- Better text and sticker handling
- Improved color picker with a history pallette
- New highlighter tool
The "contact" option in the attachments tray now brings you through an
optimized contact sharing flow, allowing you to select specific fields
to share. The contact is then presented as a special message type,
allowing you to interact with the card to add the contact to your system
contacts, invite them to signal, initiate a signal message, etc.
Previously, we were always rendering images as squares. Instead of doing
that, we now render them as close to true-to-size as possible (within
reasonable min/max width/height boundaries).
Added a FloatingActionButton to the conversation_fragment
that appears and disappears using the same logic as the
existing compose divider: appear when the conversation list
is scrolled away from the bottom, disappear when the list is
scrolled to the bottom.
