Beim Versuch, meine Flutter-App auf meinem Emulator zu debuggen, trat zufällig dieser Kompilierungsfehler auf. Ich habe versucht, mein Flutter auf die neueste Version zu aktualisieren. In meinem Code treten keine Formatierungs- oder sonstigen Fehler auf. Das einzige, was meiner Meinung nach das Problem sein könnte, ist, dass ich auf einem anderen Computer die Kodierung der Dart-Datei geändert habe, die die Ursache des Problems mit Notepad ist.

Soweit ich sehen kann, ist im Code kein Fehler. Es ist alles ganz einfacher Basiscode für eine Seite, an der ich noch nicht wirklich gearbeitet habe. Kann so etwas diesen Fehler verursachen?
Antwort1
Habe gerade meinen eigenen Gedanken bestätigt, dass es an der Kodierung des Notizblocks lag. Ich habe es auf UTF-16 geändert, obwohl UTF-8 die Standardeinstellung für Dart-Dateien ist. Ich denke, das ist bei Flutter wichtig.
