大家好，我的应用程序中有一个简单的+-按钮，我在lenove p2，note 4，k20 pro上进行了测试，效果很好，但在OnePlus 5T OxygenOs V10和Android V10上无论如何我都无法正常工作当我单击它时它不起作用，就像一个空按钮，这是代码
void showPricingSheet(context , article){
List<int> quantities = [];
List<int> serviceIds = [];
List<double> totalPrices = [];
double currentTotalPrice = 0.0;
int servicesLength;
//theses variables will be used to store values locally then send them to server
Future<List<Prices>> _prices = _fetchPrices(article['id']);
bool alreadyExc = false;
showModalBottomSheet(
isDismissible: false,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.vertical(
top: Radius.circular(20),
),
),
context: context,
builder: (BuildContext context){
var responsivenessController = ResponsivenessController(context);
return StatefulBuilder(
builder: (BuildContext context , setState){
return FutureBuilder<List<Prices>>(
future: _prices,
builder: (context , snapshot){
if(snapshot.hasData){
List<Prices> price = snapshot.data;
if(alreadyExc == false){
// initializing the list with the length provided
servicesLength = price.length;
for(int i = 0; i < price.length; i++){
quantities.add(0);
serviceIds.add(price[i].serviceId);
totalPrices.add(0);
}
alreadyExc = true;
}

DoNothingAction();

如您所见，它的简单按钮将采用商品价格并将其添加或从旧值中扣除，然后将其存储到db，但是问题不在api中，正如我提到的+-按钮在几乎所有设备上，它都能正常工作，但在5t上，由于某些原因，它无法正常工作
注意：我没有5t手机，这就是为什么我无法将其连接到PC进行调试
