Uri.parse auto replacing '+' with space in queryParameters

[viJay-beep-code]

Below sample code is auto replacing '+' character in a query parameter with space, when fetching value using queryParameters.

Uri uri = Uri.parse('https://test.com/parse?code=sf+sf+/fd3' );
print(uri.query); //print - code=sf+sf+/fd3
print(uri.queryParameters['code']); //prints - sf sf /fd3

How to solve this?

Replace + by %2B.

Thanks, I know that replacing '+' with '%2B' will result into the correct string. But is it the official way to solve this?
And is conversion from plus to space expected? What other characters need to be replaced?

[lrhn]

The conversion from + to space is expected. See #43838.

Dart's Uri class expects query parameters to be form-encoded. That seemed like a great idea at the time, but JavaScript moved in a different direction with their Url class, so now Dart is just different.
The URI parser also escapes some other characters, which are not valid in RFC-3986 URIs. Whether you expect that or not is up to you.
