Function toPlainText

toPlainText(block): string
Takes a Portable Text block (or an array of them) and returns the text value of all the Portable Text span nodes. Adds whitespace when encountering inline, non-span nodes to ensure text flow is optimal.

Note that this only accounts for regular Portable Text blocks - any text inside custom content types are not included in the output.
Parameters
- block: PortableTextBlock<PortableTextMarkDefinition, PortableTextSpan | ArbitraryTypedObject, string, string> | ArbitraryTypedObject[] | PortableTextBlock<PortableTextMarkDefinition, PortableTextSpan | ArbitraryTypedObject, string, string>[]
  Single block or an array of blocks to extract text from
Returns string
The plain-text content of the blocks
