Text class Null safety

A span of formatted text within a line in a Quill document.

Text is a leaf node of a document tree.

Parent of a text node is always a Line, and as a consequence text node's value cannot contain any line-break characters.

See also:

  • Embed, a leaf node representing an embeddable object.
  • Line, a node representing a line of text.
