ColumnDef class - schema library

Constructors

ColumnDef(String name, DataType type, {bool primaryKey = false, bool notNull = false, bool unique = false, bool autoIncrement = false, Object? defaultValue, String? defaultExprSql, String? checkExprSql, ForeignKeyRef? references, String? generatedExprSql, bool generatedStored = false, Map<String, String>? vectorSpec}): const
ColumnDef.fromJson(Map<String, Object?> j): factory

autoIncrement → bool: final
checkExprSql → String?: CHECK expression source text (column-level). The DB engine re-parses this on demand. Stored as text so it survives JSON serialization.
final
defaultExprSql → String?: DEFAULT (<expr>) source text (column-level). Mutually optional with defaultValue; when both are present defaultValue wins as the cheap fast-path for plain literals.
final
defaultValue → Object?: final
generatedExprSql → String?: GENERATED ALWAYS AS (<expr>) [VIRTUAL|STORED] source. When set, the column's value is computed from this expression at INSERT/UPDATE time.
final
generatedStored → bool: final
hashCode → int: The hash code for this object.
no setterinherited
name → String: final
notNull → bool: final
primaryKey → bool: final
references → ForeignKeyRef?: FOREIGN KEY target ("table" or "table(column)") for column-level FK.
final
runtimeType → Type: A representation of the runtime type of the object.

type → DataType: final
unique → bool: final
vectorSpec → Map<String, String>?: V30: VECTOR(dim=384, kind=hnsw, metric=cosine, ...) inline spec. Consumed by CREATE TABLE to auto-register a vector index on this column. Map keys are lowercased attribute names.
final

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.

toJson() → Map<String, Object?>
toString() → String: A string representation of this object.
