Constructors

FoundVariable({required int index, required String? name, required ColumnType type, required Variable variable, bool nullable = false, bool isArray = false, bool isRequired = false, UsedTypeConverter? typeConverter})
FoundVariable.nestedQuery({required int index, required String? name, required ColumnType type, required Variable variable, required CapturedVariable? forCaptured})

Properties

dartParameterName String
read-only, override
forCaptured CapturedVariable?
When this variable is introduced for a nested query referencing something from an outer query, contains the backing variable.
final
hashCode int
The hash code for this object.
read-only, inherited
hasSqlName bool
read-only, inherited
hidden bool
If the element should be hidden from the parameter list
final
index int
The (unique) index of this variable in the sql query. For instance, the query SELECT * FROM tbl WHERE a = ? AND b = :xyz OR c = :xyz contains three Variables in its AST, but only two FoundVariables, where the ? will have index 1 and (both) :xyz variables will have index 2. We only report one FoundVariable per index.
read / write
isArray bool
Whether this variable is an array, which will be expanded into multiple variables at runtime. We only accept queries where no explicitly numbered vars appear after an array. This means that we can expand array variables without having to look at other variables.
final
isRequired bool
final
name String?
The name of this variable, or null if it's not a named variable.
read / write, override-getter
nullable bool
Whether the type is nullable in Dart.
final
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
type ColumnType
The (inferred) type for this variable.
final
typeConverter UsedTypeConverter?
The type converter to apply before writing this value.
final
variable Variable
The first Variable in the sql statement that has this index.
final
