SchemaBuilder.toSchema constructor Null safety

  1. PersistentStore store,
  2. Schema targetSchema,
  3. {bool isTemporary = false,
  4. List<String>? changeList}

Creates a builder starting from the empty schema.

If store is null, this builder will emit commands that are Dart statements that replicate the methods invoked on this object. Otherwise, commands are SQL commands (for the database represented by store) that are equivalent to the method invoked on this object.


SchemaBuilder.toSchema(PersistentStore store, Schema targetSchema,
    {bool isTemporary = false, List<String>? changeList})
    : this.fromDifference(
          store, SchemaDifference(Schema.empty(), targetSchema),
          isTemporary: isTemporary, changeList: changeList!);
