Fix NullPointerException

✅ Solution

NullPointerException in Flutter often arises when you're trying to use a variable or object that hasn't been initialized or is unexpectedly null. To fix this, ensure all variables are properly initialized before use, and use null-aware operators (?. , ??) or null checks (if (variable != null)) to safely access properties and methods of potentially null objects. Carefully examine logs and stack traces to pinpoint where the null value is unexpectedly encountered.
