I have the following issue:

Passing an empty for DSN does not continue to run the application.

When passing in null an exception is thrown with the message: 'DSN is required. Use empty string to disable SDK.' If you pass an empty string the _init method returns without executing appRunner.

Is this expected behavior? I would have still expected my application to run with sentry disabled.

Steps to reproduce:

• Run a full application with sentry init and pass an empty string for the dsn value. e.g.
  await SentryFlutter.init((options) {
  options.dsn = "";
  }, appRunner: () {
  ...code to run application
  });

Actual result:

• Application is not run

Expected result:

• Application should still be run

@JonathanSiddle thanks, will check this out asap

Just an update on this, one of my colleagues managed to get it working, the exception I was getting says you need to pass an empty string, passing '', does not seem to work but passing a string with a ' ' does seem to disable the SDK and continue to start the application as normal

@JonathanSiddle makes sense, it's a bug actually and we've fixed it already, it'll be included in the next version, thanks for reporting.
