seems Dart is totally garbage

from clima-flutter-completed.

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

from clima-flutter-completed.

I got the similar problem. I used var then it got solved.

Hi, I solved using var temp

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

thanks @Rohan2309

from clima-flutter-completed.

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();

from clima-flutter-completed.

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();

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

from clima-flutter-completed.

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.
