fromExistingSession function Null safety

Future<WebDriver> fromExistingSession(
  1. String sessionId,
  2. {Uri? uri,
  3. WebDriverSpec spec = core.WebDriverSpec.Auto}

Creates an async WebDriver from existing session using AsyncIoRequestClient.

This will bring in dependency on dart:io. Note: WebDriver endpoints will be constructed using resolve against uri. Therefore, if uri does not end with a trailing slash, the last path component will be dropped.


Future<core.WebDriver> fromExistingSession(String sessionId,
        {Uri? uri, core.WebDriverSpec spec = core.WebDriverSpec.Auto}) =>
        (prefix) => AsyncIoRequestClient(prefix), sessionId,
        uri: uri, spec: spec);
