IterableConversionX<E> extension

Type conversion helpers for non-null Iterable collections.

Provides index-based element access with automatic type conversion. Each method extracts the element at the specified index and converts it to the target type using the convert_object infrastructure.

Example

final data = ['42', '3.14', 'true'];
final intVal = data.getInt(0);       // 42
final doubleVal = data.getDouble(1); // 3.14
final boolVal = data.getBool(2);     // true

All methods support nested navigation via innerMapKey and innerIndex for complex structures like List<Map<String, dynamic>>.

See also: NullableIterableConversionX for nullable-safe variants.

Available on Iterable<E>, provided by the IterableConversionX extension

Converts the element at index to a Map of K2 to V2.

getNum(int index, {dynamic innerMapKey, int? innerIndex, String? format, String? locale, num? defaultValue, ElementConverter<num>? converter}) → num

Available on Iterable<E>, provided by the IterableConversionX extension

Converts the element at index to a num.

mapList<R>(R mapper(E e), {ElementConverter<R>? converter}) → List<R>

Available on Iterable<E>, provided by the IterableConversionX extension

Maps the elements and eagerly materializes them into a List using convert_object.

toMutableSet({ElementConverter<E>? converter}) → Set<E>

Available on Iterable<E>, provided by the IterableConversionX extension

Returns this iterable as a mutable Set using the centralized conversion logic.
