error

and when I try to click the error it directs me to this class and directs it to SafeArea

Solution

Try with the following code may be it will help you because your error is clear it saying null check should be apply on nullable object.

    // you can apply null handling on that line where it showing error
    var title = text;
    if (title != null) {
        var len = title.length; // Safe
    }


    //or use default null safety operator
    Use ?. and ??
    
    var len = title?.length ?? 0; // Provide a default value if title is null.
