我遇到以下错误
MainScreen file:///C:/Users/Chris/AndroidStudioProjects/taxi_rider/lib/main.dart:77:32
When the exception was thrown, this was the stack:
#2 new CameraPosition (package:google_maps_flutter_platform_interface/src/types/camera.dart:24:16)
#3 _MainScreenState.build (package:taxi_rider/UI/views/MainScreen.dart:180:40)
#4 StatefulElement.build (package:flutter/src/widgets/framework.dart:4612:27)
#5 ComponentElement.performRebuild (package:flutter/src/widgets/framework.dart:4495:15)
#6 StatefulElement.performRebuild (package:flutter/src/widgets/framework.dart:4667:11)
相关的导致错误的小部件是：

这是我的代码
function onEdit(e){
const src = e.source.getActiveSheet();
const r = e.range;
if (r.rowStart == 1 || r.columnStart != 1) return;
let dest;
if (src.getName() == "Sheet1")
dest = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet2");
else if (src.getName() == "Sheet2")
dest = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1");
src.getRange(r.rowStart,1,1,1).moveTo(dest.getRange(dest.getLastRow()+1,1,1,1));
src.deleteRow(r.rowStart);
}
