RingView lineCap тень видна, когда прогресс> 100

Question

Я получил этот кодовый код от https://www.youtube.com/watch?v=H7bsJ0rPgN4&t=898s. Код прекрасно работает со значениями stati c, но когда я добавил свои, он сделал эту забавную строку cap. Я сузил его до тени на перекрывающемся кольцевом представлении, но я понятия не имею, почему он применяет его к кольцу, которое имеет значение до 1,0.

//> Here is where I think the problem is and I'm not sure how to make a state property with a ternary operator to fix the issue.
