parseId<T> method

T parseId <T>(
  1. dynamic id
)

Transforms an id (whether it is a String, num, etc.) into one acceptable by a service.

The single type argument, T, is used to determine how to parse the id.

For example, parseId<bool> attempts to parse the value as a bool.

Implementation

static T parseId<T>(id) {
  if (id == 'null' || id == null) {
    return null;
  } else if (T == String) {
    return id.toString() as T;
  } else if (T == int) {
    return int.parse(id.toString()) as T;
  } else if (T == bool) {
    return (id == true || id?.toString() == 'true') as T;
  } else if (T == double) {
    return double.parse(id.toString()) as T;
  } else if (T == num) {
    return num.parse(id.toString()) as T;
  } else {
    return id as T;
  }
}
