printSink property

void Function(String message)? printSink

Print interceptor for the flutter_agent_memory package's bare print() debug logs (gh-1510). The package logs with // ignore: avoid_print on the calling isolate; in TUI mode stdout IS the terminal, so those raw bytes interleave with the frame protocol, physically clobber cells, and the cell-diff renderer then skips repainting "unchanged" cells against the desynced grid — the screen buffer loses characters (memory round-tripcomplete). Every package-facing op runs inside a zone whose print delegates here; the CLI wires its diagnostic log. Null keeps the package's default print behavior (headless/embedders).

Implementation

final void Function(String line)? printSink;
