QUESTION
I am working with a flutter app. I am trying to display data from a json.
I am stuck on the following error:
LateInitializationError: Field 'data' has not been initialized error
My main.dart file is as follows:
...ANSWER
Answered 2022-Apr-10 at 16:37late 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.

Answered 2022-Apr-09 at 21:23a few issues with the code.
- the
restaurant
variable you provided doesnt need to be "jsonified", you can use it as is. - the path
/restaurant/city
is supposed to have thecity
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:

QUESTION
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:
...ANSWER
Answered 2022-Feb-02 at 19:02The 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).

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

This is the dataframe I get after logic is applied.

Answered 2021-Dec-17 at 11:39Assuming 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:-
