fromString static method

CustomProxy? fromString({ required String proxy, })

Creates a CustomProxy instance from a string representation.

The proxy string should be in the format "ipAddress:port". For example: "192.168.1.1:8080"

Returns null if:

• The proxy string is empty
• The port number cannot be parsed to an integer

Throws an AssertionError in debug mode if the proxy string is empty.

Implementation

static CustomProxy? fromString({required String proxy}) {
  // Check if the proxy string is empty
  if (proxy.isEmpty) {
    assert(
      false,
      'Proxy string passed to CustomProxy.fromString() is invalid.',
    );
    return null;
  }

  // Split the proxy string into parts and extract the IP address and port number if available
  // Format: "ipAddress:port"
  final proxyParts = proxy.split(':');
  final ipAddress = proxyParts[0];
  final port = proxyParts.isNotEmpty ? int.tryParse(proxyParts[1]) : null;

  return CustomProxy(ipAddress: ipAddress, port: port);
}
