颤振：参数类型"字符串"不能分配给参数类型'Uri'

Question

我得到这个错误，而在扑动建设项目在"url"。

代码:

void addProduct(Product product) {
const url = 'https://flutter-update.firebaseio.com/products.json';
http.post(url, body: json.encode({   <-- here 
'title': product.title,
'description': product.description,
'imageUrl': product.imageUrl,
'price': product.price,
'isFavorite': product.isFavorite,
}),);

Answer 1

尝试一下const url = Uri.parse('https://flutter-update.firebaseio.com/products.json');
