sortedIndex function
Uses a binary search to determine the lowest index at which value should be inserted into list in order to maintain its sort order. Returns the index at which value should be inserted into list. Example
_.sortedIndex([30, 50], 60);
// Returns 2
_.sortedIndex([30, 50], 40);
// Returns 1
_.sortedIndex([30, 50], 30);
// Returns 0
Implementation
int sortedIndex(List list, dynamic value) {
return baseSortedIndex(list, value);
}
