Entry.fromString constructor

Entry.fromString(ExtractSettings settings, String value)

Parses the string representation of Entry

This method never fails. It tries to create an instance of Entry from any string. Therefore, it is not good to use it for validation.

Implementation

factory Entry.fromString(ExtractSettings settings, String value) {
