RangeError (index): Invalid value: Valid value range is empty: 0

場景

最近在學習flutter,運行時碰到了這個錯誤。
I/flutter (25300): ══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
I/flutter (25300): The following RangeError was thrown building Home(dirty, state:

════════════════════════════════════════════════════════════════════════════════════════════════════
I/flutter (25300): Another exception was thrown: RangeError (index): Invalid value: Valid value range is empty: 0

原因

在google上查了下，這是因爲flutter使用gradle構建時出現的問題。

解決方法

在Android Studio中打開terminal下，運行 flutter clean

$ flutter clean

兩次運行項目就正常了。
