I'm using Dio, this code is working for me:
static Future<Map<String, dynamic>> createcustomer() async {
try {
var data = {
'name': 'Jenny Rosen',
'address': {
'line1': '510 Townsend St',
'postal_code': '98140',
'city': 'San Francisco',
'state': 'CA',
'country': 'US',
}
};
Response response = await Dio().post('https://api.stripe.com/v1/customers',
data: data,
options: Options(contentType:Headers.formUrlEncodedContentType,
headers: {
'Authorization': 'Bearer ${secret}', // your secret key
}
),
);
print('response: ${jsonDecode(response.data)}');
return jsonDecode(response.data);
} catch (err) {
print('err charging user: ${err.toString()}');
}
return null;
}

I have used this api is working fine but response is paramter unknown
{error: {code: parameter_unknown, doc_url: https://stripe.com/docs/error-codes/parameter-unknown, message: Received unknown parameter: {"address":"sss","email":"aryan#gmail.com","name":"aryan","phone":"953667"}, param: {"address":"sss","email":"aryan#gmail.com","name":"aryan","phone":"953667"}, type: invalid_request_error}}
Flutter Code
Future createcustomer() async {
try {
var body = {
"address": "sss",
"email": "aryan#gmail.com",
"name": "aryan",
"phone": "95366710",
};
//final response = await http.post(Uri.parse("https://api.stripe.com/v1/customers"),
final response = await http.post(Uri.parse("https://api.stripe.com/v1/customers"),
headers: {
"Content-Type": "application/x-www-form-urlencoded","Authorization": "Bearer ${sKey}",
},
body: json.encode(body),
);
print('resvfdg: ${jsonDecode(response.body)}');
return jsonDecode(response.body);
} catch (err) {
print('err charging user: ${err.toString()}');
}
}
