compoundIndices method
The relevant indices inside container (by default the current
index).
Implementation
List<FormIndex> compoundIndices([FormIndex? container]) {
container ??= _currentFormIndex;
final indices = <FormIndex>[];
var walker = incrementIndex(container);
while (FormIndex.isSubElement(container, walker)) {
if (isIndexRelevant(walker)) indices.add(walker);
walker = incrementIndex(walker);
}
return indices;
}
