Reason for failure/description

The SlackLogger test file fails to load due to compilation errors when trying to assign to a constructor:

Failed to load "test/drivers/slack_logger_test.dart":
test/drivers/slack_logger_test.dart:38:23: Error: Can't assign to this.
      http.Client.new = () => httpClient;

test/drivers/slack_logger_test.dart:134:23: Error: Can't assign to this.
      http.Client.new = () => httpClient;

The error occurs in two places where the test is attempting to mock the HTTP client by assigning to its constructor, which is not allowed in Dart.

Is this a regression?

No

Additional context

• Location: packages/log/test/drivers/slack_logger_test.dart
• This is a compilation error rather than a runtime test failure
• The test is attempting to mock HTTP client behavior incorrectly
• The error appears in two different test cases within the same file
