【填坑】Unhandled Exception: type 'List' is not a subtype of type 'String' in type cast

 

原代码：

var Params = {
  "tokens":["1"],
  "data": "123",
};
final response = await http.post(url, body: Params); //post请求

解决办法：

Map<String, dynamic> body = {
  "tokens":["1"],
  "data": "123",
};
var response = await Dio()
    .post("http://192.168.1.100:4001/api",data: body);
print(response);
