NullPointerException in FlutterTestReportParser when trying to run sonar-scanner

[hemmesdev]

Hi, i got a problem running sonar scanner with flutter plugin. I'm getting a NullPointerException in the FlutterTestReportParser

15:32:43.766 ERROR: Error during SonarQube Scanner execution
java.lang.NullPointerException
	at fr.insideapp.sonarqube.flutter.tests.FlutterTestReportParser.parse(FlutterTestReportParser.java:58)
	at fr.insideapp.sonarqube.flutter.tests.FlutterTestReportParser.parse(FlutterTestReportParser.java:42)
	at fr.insideapp.sonarqube.flutter.tests.FlutterTestSensor.execute(FlutterTestSensor.java:57)

The problem is cause by an empty line in the tests.output.

flutter test --machine > tests.output

The output that i am getting has an empty line at the end of the file.

{"protocolVersion":"0.1.1","runnerVersion":null,"pid":18104,"type":"start","time":0}

{"testID":3,"result":"success","skipped":false,"hidden":false,"type":"testDone","time":3624}
{"success":true,"type":"done","time":3667}

When it gets parsed in the FlutterTestReportParser.parse method on line 46 it throws a NullPointerException because:

String[] lines = input.split(System.getProperty("line.separator")); // also returns the empty lines
for (int i = 0; i < lines.length; i++) {
    String line = lines[i];
    JSONObject obj = (JSONObject)JSONValue.parse(line); // is null if its an empty line

    // Suites
    if (obj.containsKey("suite")) { // if obj is null this wil result in a NullPointerException

Could you please add a null check on the "JSONObject obj" in the FlutterTestReportParser.parse?
