v0.19.0

• Adds tapIf() to all Elements. Works the same as tap(), but allows you to specify a condition to decide if the tap is needed.
• Adds blocks() methods to all Surfaces for adding arrays/iterables of blocks easily.
• Adds support for callbackId, externalId, and privateMetadata to AppHome surfaces. This was previously missing.
  • This was done by creating a base View surface class that both Modal and AppHome extend.
• Adds the encodePrivateMetadata(array $data) method to Modal and AppHome, which provides an easy way to set encoded private metadata from an array.
• Adds support for the newInput() method to all surfaces, instead of just Modals.
• Updates all VirtualBlocks to implement IteratorAggregate for emitting it's BlockElements.
