Meine Anforderung ist die Art des Bildes unten. Meine Navigationsleiste sollte von der rechten Seite geöffnet werden. Ich habe das umgesetzt. Meine Navigationsschublade öffnet sich von rechts nach links. Das Problem ist jedoch, dass sich das Umschalt-Symbol immer auf der linken Seite befindet. Wie kann ich das Umschalt-Symbol rechts einstellen? Ich habe die folgende SO-Frage geprüft, aber keine von ihnen hat geholfen.

Change toggle button image Icon In der Navigationsleiste von rechts nach links

Schublade In rechte Schublade wechseln

Hier ist, was ich versucht habe.
