id property

String? id

Stable developer-defined column identity.

When provided, the grid uses this value to preserve column runtime state such as width, pinning, sorting, filtering and summary overrides across parent rebuilds, inserts, removes and reorders. Public grid controller column commands also target columns by this id. If omitted, the grid falls back to a best-effort identity for internal layout state, but the column cannot be targeted by controller column commands.

Implementation

final String? id;
