Story Block

For android:
StoryBlock is a heavy object containing multiple instances of the player, Heavy-lifting UI elements, and intensive background tasks, Beware that the recommended number of the StoryBlock being used in a single screen is 1. However, in a wide range of new Android devices, 2 instances might work alright. Any number of StoryBlock above this limitation is not recommended by the Firework team and is not supported.
Currently, there are five source types of the story block:
  • Discover
  • Channel
  • Playlist
  • Dynamic Content
  • Hashtag Playlist
  • SKU

Floating Player

You could set enablePictureInPicture to true to enable the floating player.
StoryBlock(
height: 400,
source: StoryBlockSource.discover,
enablePictureInPicture: true,
);

OS Picture in Picture

You also need to set enablePictureInPicture to true to enable the OS Picture in Picture.
StoryBlock(
height: 400,
source: StoryBlockSource.discover,
enablePictureInPicture: true,
);
This feature allows the user to watch media while the application is in a background state. While in background mode a video will display in a floating, resizable window.

Set up the iOS project

To enable PiP functionality, you also need to add Background Modes capability via Signing & Capabilities in your iOS project settings. More information about this can be found here: Apple Documentation
To use Picture in Picture, we configure the app to support background audio playback. See Configuring the Audio Playback of iOS and tvOS Apps for more details.

Keep alive when scrolling the widget out of the view box

Generally, if you put the story block widget as the child of ListView, it will be rebuilt when scrolling the widget out of the view box. You could set wantKeepAlive as true to make the story block widget keep alive when scrolling the widget out of the view box.
StoryBlock(
height: 400,
source: StoryBlockSource.discover,
// Keep the widget alive when scrolling the widget out of the view box
wantKeepAlive: true,
);
