SchemaRenames constructor

const SchemaRenames({
  1. Map<String, String> tables = const {},
  2. Map<String, Map<String, String>> columns = const {},
})

Declares intentional renames without inferring them from schema similarity.

Maps are retained as provided. Diff generation validates targets and rejects swaps or chains that need explicit intermediate migration steps.

Implementation

const SchemaRenames({this.tables = const {}, this.columns = const {}});
