Flutter:将removeAt应用于包含嵌套对象的列表

class NestedObject {
  String name;
  
  NestedObject(this.name);
}

void main() {
  List<List<NestedObject>> nestedList = [
    [NestedObject('Object 1'), NestedObject('Object 2')],
    [NestedObject('Object 3'), NestedObject('Object 4')],
    [NestedObject('Object 5'), NestedObject('Object 6')],
  ];
  
  // 删除索引位置为1的嵌套对象
  nestedList[1].removeAt(1);
  
  print(nestedList);
}

[
  [Instance of 'NestedObject', Instance of 'NestedObject'],
  [Instance of 'NestedObject'],
  [Instance of 'NestedObject', Instance of 'NestedObject']
]
