Gridlayout is stupid (or me)

I've had horrible experiences with this framework, I just don't understand where these spacings between the lines of my grid come from.

Der Bericht enthält nur einen Screenshot, eine Beschreibung unerwarteter Abstände im Grid und Abhängigkeitsversionen; er nennt keine Repository-Datei, keinen Test und kein reproduzierbares Layout. Beginne damit, das GridLayout-Markup und die Styles aus dem angehängten Beispiel zu identifizieren, und reproduziere dann die Abstände mit den aufgeführten NativeScript- und Angular-Versionen. Abgeschlossen ist die Aufgabe, wenn die Ursache der Abstände isoliert wurde und das erwartete Layout-Verhalten dokumentiert oder verifiziert ist.
