Single quotation marks in data table are not being espaced

(package version: flutter_gherkin: ^3.0.0-rc.9)

If there is a single quotation mark in a data table, it will not be escaped and the test file will not generated as a result.

Let's take for example the following feature file:

# language: en
Feature: Check users
    Scenario: Check users descriptions
        Given I am logged in
        When I press "Users"
        Then I expect the following results
            | user   | user_description                                          |
            | John   | I am a college student                                    |
            | Robert | I'm a tester                                              |

When we try generate the test file, we get the following error:

[SEVERE] flutter_gherkin:gherkin_test_suite on integration_test/gherkin_suite_test.dart:
An error `FormatterException` occurred while formatting the generated source for
  `asset:application/integration_test/gherkin_suite_test.dart`
which was output to
  `integration_test/gherkin_suite_test.gherkin_tests.g.part`.
This may indicate an issue in the generator, the input source code, or in the
source formatter.
Could not format because the source could not be parsed:
