Don't enable `print()` breadcrumbs by default on Flutter

Platform:

• Dart
• Flutter Android or iOS
• Flutter Web

Sentry Flutter Version 5.1.0

By default Flutter calls dumpErrorToConsole for every exceptions which it catches. If you go down the rabbit hole, you'll end up here. As you can see it calls print().

This results in pretty bad breadcrumbs because each stacktrace frame is written as a single breadcrumb.

This seems to be an issue on debug and release builds.

@ueman should we investigate this? we don't want to flood crumbs

[ueman]

It should be disabled by default (or just on Flutter).
I haven't come around to do this yet, though. The documentation should probably mention this behavior, too, in case a user manually enables this.

I don't think we need further investigation as the reason for this behavior is already explained in the issue. Or do you mean something else?

@ueman I meant, we should fix this, sorry :D
