 Additionally, columns that have the type name `BOOLEAN` or `DATETIME` will have

 Booleans are stored as `INTEGER` (either `0` or `1`). Datetimes are stored as

+For integers that should be represented as a `BigInt` in Dart (i.e. to have better compatibility with large numbers when compiling to JS),

 Dart enums can automatically be stored by their index by using an `ENUM()` type
 referencing the Dart enum class:
