deepMerge function

Map<String, dynamic> deepMerge(Map<String, dynamic> object, Map<String, dynamic> other)

Deeply merges nested properties, returning a new Map.

Properties of other will overwrite properties of object.

Implementation

Map<String, dynamic> deepMerge(
  Map<String, dynamic> object,
  Map<String, dynamic> other,
) {
  return {
    ...object,
    for (var entry in other.entries)
      entry.key: object[entry.key] is Map<String, dynamic> &&
              entry.value is Map<String, dynamic>
          ? deepMerge(object[entry.key], entry.value)
          : entry.value
  };
}
