@simplygkgk @Samikhanonco instead of double temp replace it with var temp

[azeemgujjar]

seems Dart is totally garbage

Hi, I solved using var temp

    var temp = weatherData['main']['temp'];
    temperature = temp.toInt();

thanks @Rohan2309

i observed that for some cities or (latitude and longitude), the JSON return temperature as int, example like below (23 not 23.00)
{coord: {lon: -xxx, lat: xxx}, weather: [{id: 800, main: Clear, description: clear sky, icon: 01n}], base: stations, main: {temp: 23

so 23 is int not double. so i made generic change to convert it to double and then it works well.
setState(() {
double temp = (weatherData['main']['temp']).toDouble();

[rohitsinghkcodes]

just initialize temperature with int then store the fetched location's temperature temporarily in var at last typecast it in int
int temperature;
.
.
var temp = weatherData['main']['temp'];
temperature = temp.toInt();

Avoid use of var. Its better to use dart as strongly tyoed.

unfortunately , I have the sem issue but the solution isn't workin well with my case

use var

No ... use num instead of double in this case. Always avoid var when possible.

  num? temperature;
  temperature = weatherData['main']['temp'];

or

  num temperature = 0.0;
  temperature = weatherData['main']['temp'];

I consider it also bad API design when numeric values flip between double and int in json, but unfortunately we have to deal with it in this case.

@zoenie123 , There is a workaround if the json data flips between double and int. This helped me. Take a look.

@rifat-22 I stand with my solution, it's the most simple and fast one. All other versions I have seen do conversion on conversion. No need.
