safeJsify function

JSAny? safeJsify(dynamic value)

Safely converts Dart values to JavaScript-compatible types for web interop.

This function handles the conversion of various Dart types to their JavaScript equivalents using the appropriate JS interop methods.

Accepted input types:

• JSAny - Returned as-is to avoid double conversion
• Map - Converted using .jsify() to a JavaScript object
• List - Converted using .jsify() to a JavaScript array
• DateTime - Converted using .jsify() to a JavaScript Date object
• bool - Converted using .toJS to a JavaScript boolean
• num (int/double) - Converted using .toJS to a JavaScript number
• String - Converted using .toJS to a JavaScript string
• Any other type - Logs a warning and returns null to prevent JS interop issues

Return value: Returns a JSAny? which represents the JavaScript-compatible value. The return type is nullable to handle cases where the input cannot be converted or is already null.

Null handling:

• If the input value is null, it is explicitly checked and returned immediately
• The function is null-safe and will not throw on null inputs

Example usage:

Convert a Map to JavaScript object
var jsObj = safeJsify({'key': 'value', 'count': 42});

Convert a List to JavaScript array
var jsArray = safeJsify([1, 2, 3, 'four']);

Handles null gracefully
var jsNull = safeJsify(null); // Returns null

Implementation

JSAny? safeJsify(dynamic value) {
  if (value == null) {
    return null;
  } else if (value is Map) {
    return value.jsify();
  } else if (value is List) {
    return value.jsify();
  } else if (value is DateTime) {
    return value.jsify();
  } else if (value is bool) {
    return value.toJS;
  } else if (value is num) {
    return value.toJS;
  } else if (value is String) {
    return value.toJS;
  } else {
    debugPrint(
        '[Mixpanel] Warning: Unsupported type for JS conversion: ${value.runtimeType}. '
        'Value will be ignored. Supported types are: Map, List, DateTime, bool, num, String, JSAny, and null.');
    return null;
  }
