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.
QUESTION
I have a dataset with two columns on_road
and at_road
, the combination of which make up a string called geocode_string
. With this string, I wish to geocode these intersections using my google API key. As an example, I have on_road = Silverdale
and at_road = W 28th St
, which combine to form geocode_string = Silverdale and W 28th St, Cleveland, OH
.
However, when I try and use the geocode
function from ggmap
, I get this message: "SILVERDALE and W ..." not uniquely geocoded, using "silverdale ave, cleveland, oh 44109, usa"
.
It seems in this case that R just assumes a location by default, in this case just silverdale ave
. I would like to have R not do this- perhaps just to leave blank the locations for which a unique geocode cannot be found. I can then go through and manually find the coordinates for such cases. I just would like to flag the observations in some way.
I'd also like to point out that in the second row of the dataset, I get S MARGINAL RD and W 93RD ST , CLEVELAND , OH
, an intersection that does not exist in Cleveland. When I paste that string into google maps, it seems to search for a partial match and gives me the coordinates for S Marginal Rd
. Any thoughts why an intersection that does not exist would generate coordinates in this case, but not the Silverdale
case described above? Is there any way to prevent this from happening?
I would greatly appreciate any help!
...ANSWER
Answered 2022-Mar-09 at 16:50I faced a similar problem. The best solution I could come up with was to alter the "geocode" function, that you can find at github here
I included two extra columns: column 'status': informs the number of matches per address. Therefore, you can easily spot where "not uniquely geocoded, using" happened. I also included column address2 to inform what is the second found address (in cases where status > 1).
I did that by including the following parts marked as 'new'

QUESTION
Hi I have a small android app that demonstrates 2 fragments in 1 activity, it should just be a simple code but I am getting a null pointer exception. The app is just a listview in 1 fragment, and an edittext in the other and it connects the main activity. My book is from 2016 so I think some of these things were depreciated that why I am having the error. The text should change in the other fragment after pressing the listview options. Also I am supposed to save the instance state but I haven't got that far yet. I believe the error is from the listener. OnFragmentInteractionListener that it points to null, I can comment the line. Thanks. Code below:

Solution: use https://www.npmjs.com/package/jsonrepair module. It detected the bad lines and fixed them, this is likely what google does (some sort of JSON repair).
PS: I tried https://www.npmjs.com/package/json-fixer without success
