Currently i have a cart application and use hive package to save data cart on memory. When i use normally the app, the quantity of cart show properly grouped. These is the code for deduplicate the items and show their quantity grouped
Map productsQuantity(List<Product> localProducts) {
var result = {};
for (var singleProduct in localProducts) {
if (!result.containsKey(singleProduct)) {
result[singleProduct] = 1;
} else {
result[singleProduct] += 1;
}
}
return result;
}
It's works fine ... but when i refresh the page the items are ungrouped
Before refresh the page, the cart show 5 items and this is expected
2 items of X product
3 items of Y product
After refresh this is the output:
1 item X
1 item X
1 item Y
1 item Y
1 item Y
