假設我的串列 1 資料是這樣的
[
{
key1: value1,
key2: value2,
key3: value3,
},
{
key1: value4,
key2: value5,
key3: value6,
},
.....
]
如果我想發送怎么辦
{
key1: value4,
key2: value5,
key3: value6,
},
到索引 1 處的更新串列
我的代碼是：
updatedList[0]= List.from(widget.allDataList[1]);
uj5u.com熱心網友回復：
void main() {
var list = [];
list =
[
{
"key1": "value1",
"key2": "value2",
"key3": "value3",
},
{
"key1": "value4",
"key2": "value5",
"key3": "value6",
},
];
List<Map<String, String>> updatedList=[];
updatedList.insert(0, list[0]);
print(updatedList);
}
