request: intl with arb files

[mars3142]

Is there an existing feature request for this?

• I have searched the existing issues.

Command

I would like to use multilanguage tests with AppLocalizations (intl)

Description

We wanted to test multiple languages for the widgets.

Reasoning

For correct testing it is important to test the widget behavior with multiple languages. We use the default intl package for bundle texts.
