Static Methods

cloneFragment(Fragment source, {String? text}) → Fragment: Creates a new fragment with the same styles as the source fragment. If text is provided, uses that text; otherwise uses the source fragment's text.
collectLeafFragments(FNode node) → List<Fragment>: Recursively collects all leaf fragments in order. A leaf fragment is a Fragment that is not an InlineContainerNode.
createFragmentWithPendingStyles(FluentDocument document, String text) → Fragment: Creates a new fragment with styles from the document's pending styles. Used when inserting new text at the cursor position.
deleteTextInFragment(Fragment fragment, int offset, {int count = 1}) → bool: Deletes count characters from fragment starting from offset. Returns false if the range is invalid. Optimised edge cases avoid temp substring allocations.
insertTextInFragment(Fragment fragment, int offset, String text) → bool: Inserts text in fragment at offset. Returns false if offset is out of range. Optimised edge cases (prepend / append) avoid temp substring allocations.
mergeFragments(Fragment fragment, Fragment next) → void: Merges next into fragment (concatenates the text, then next must be removed from the container by the caller).
splitFragment(Fragment fragment, int offset) → ({Fragment left, Fragment right}): Splits fragment at offset: returns (left, right). The original fragment is mutated (becomes the left part). The right part is a new Fragment with the same style (cloneFragment).
