這是我的演示 json 回應。假設我想顯示所有資料，"CategoryList但我不顯示"CategoryName": "NEW ARRIVALS",我的應用程式中的串列。如何忽略來自我的 Json 回應的特定資料？我可以按關鍵字過濾掉New嗎？
如果New關鍵字進入CategoryName將忽略整個串列

我的 Ui 部分在我的應用程式螢屏中顯示資料。
FutureBuilder(

if (snapshot.connectionState != ConnectionState.done) {
return Center(
child:

CupertinoActivityIndicator());
}
if (snapshot.hasError) {
return Text(
"Somthing went wrong. Please try after some time.");
}
if (snapshot.hasData) {
return ListView.builder(

uj5u.com熱心網友回復：
您可以將此過濾器應用于串列，然后再將其發送給構建器
categoryList.removeWhere((element) => element.CategoryId == '12');
