datadog_flutter v1.7.0: App crashes when extraInfo property in setUserInfo method is null

[mkobuolys]

datadog_flutter v1.7.0: App crashes when extraInfo property in setUserInfo method is null. Based on the changelog, this problem should have been appeared since datadog_flutter v1.5.2 with BREAKING CHANGE all attribute maps have been updated from Map<String, dynamic> to Map<String, Object>. These Maps no longer support nullable values.

This is the error from the native layer:

datadog_flutter/SwiftDatadogFlutterPlugin.swift:327: Fatal error: 'try!' expression unexpectedly raised an error: Swift.DecodingError.valueNotFound(Swift.Dictionary<Swift.String, AnyCodable.AnyCodable>, Swift.DecodingError.Context(codingPath: [], debugDescription: "The given data did not contain a top-level value.", underlyingError: nil))

This error occurs when calling the setUserInfo method like this:

DatadogFlutter.setUserInfo(
  id: '123',
  email: 'email@test.com',
);

You can fix the problem by providing an empty object to extraInfo.

DatadogFlutter.setUserInfo(
  id: '123',
  email: 'email@test.com',
  extraInfo: {},
);

I think you should either specify the default value for extraInfo (e.g. empty object) or fix the bug in the native layer to expect a nullable value.
