Я пытаюсь выполнить действие на основе API Google map, которое покажет текущее местоположение.
У меня также есть тонны кода, и я не смог найти проблему.
Я получаю ошибка на выходе сборки:

Я вдруг получил эту ошибку, когда Я видел видео на YouTube, которое объясняет код.
Я ищу решение этой проблемы, но не знаю, с чем это связано.
