Future<Map<String, dynamic>?> createSubscriptionIntent(String priceId, String customerId) async {
// Get current time in seconds since epoch
int? trialEnd;
int currentTime = DateTime.now().millisecondsSinceEpoch ~/ 1000;
// Calculate trial end time
trialEnd = currentTime + (2 * 24 * 60 * 60); // Convert days to seconds

try {
Map<String, dynamic> body = {
'customer': customerId,
'items[0][price]': priceId,
// 'trial_end': trialEnd.toString(),
'payment_behavior': 'default_incomplete',
'expand[]': 'latest_invoice.payment_intent',
};

var response = await http.post(
Uri.parse('https://api.stripe.com/v1/subscriptions'),
headers: {
'Authorization': 'Bearer $key', // Replace with your Stripe Secret Key
'Content-Type': 'application/x-www-form-urlencoded',

);

var jsonResponse = json.decode(response.body);
print('Subscription Response: $jsonResponse');

if (jsonResponse.containsKey('latest_invoice')) {
var paymentIntent = jsonResponse['latest_invoice']['payment_intent'];
if (paymentIntent != null && paymentIntent.containsKey('client_secret')) {
