            How to fix "LateInitializationError: Field 'data' has not been initialized error"
            Asked 2022-Apr-10 at 18:45

            I am working with a flutter app. I am trying to display data from a json.

            Answered 2022-Apr-10 at 16:37

            late List data; should change to List? data;. If something is non-nullable but late, it relies on the developer to make sure this variable is initialized before it is used. Since it's used in the build method, in data == null ? 0 : data.length;, it will throw an error.

            Changing it to a nullable List? fixes this.

            a few issues with the code.

            1. the restaurant variable you provided doesnt need to be "jsonified", you can use it as is.
            2. the path /restaurant/city is supposed to have the city as a variable from the user, to achieve that you need to declare the decorator as below. Also now the "city" is argument to the method too:

            Searching for category with subcategories in javascript array of objects

            I'm building a search functionality where I need to search for a specific value to be find by part of its text. So I've got an example object:



            Answered 2022-Feb-02 at 19:02

            The issue is your map() call. It will return an Object (your org) if it has at least one client that passes the filter(), but implicity returns undefined if filtered.length is not greater than zero.

            In JS every function has a return -- either declared with return, or implicit. The default implicit value is undefined which is where those array entries are coming from. You could switch map() to filter() and it should work (since it will omit the falsy undefined values from the array).

            Python script module not found on rerun of script
            Asked 2022-Feb-01 at 20:37

            I am running a python script on RaspberryPi 4, and today when I ran the script again, it showed me the error ModuleNotFoundError: No module named 'adafruit_ssd1306' although I ran this same script yesterday about 10 times, it ran perfectly without any errors. I did not change anything in the script, not even its location. I tried force reinstalling the library, running the script from another location, rebooting the pi, running it as sudo but none of them worked either. By using pip3 freeze it shows that the package is installed and trying to install the package again says that the requirement is already satisfied.

            Pandas: Merge values from one dataframe to another based on condition
            Asked 2021-Dec-17 at 11:48

            using fuzzy logic and fuzzywuzzy module I am able to match Names(from one dataframe) with Short Names(from another Dataframe). Both these Dataframes also contain a table ISIN.

            This is the dataframe I get after logic is applied.



            Answered 2021-Dec-17 at 11:39

            Assuming your first dataframe has ISINs filled out to null, then a simple merge will do what you need. If you need the non-null ISINs in the first dataframe to be preserved, then you need to use a boolean mask:-
