Is your feature request related to a problem? Please describe.

Cannot use intl 0.20.0 with web 1.0.0.

In intl 0.20.0 a deps to web package was introduce, but a deps to ^0.5.0, web is now released in 1.0.0 and many packages (like url_launcher) support both by adding deps as web: ">=0.5.1 <2.0.0"

Describe the solution you'd like

replace in pubspec.yaml:

web: ^0.5.0 to web: ">=0.5.1 <2.0.0"

Describe alternatives you've considered
