I want to get multiple String parameters as form data under the body section, using #RequestParam doesn't recognise form data. And how to use #RequestBody for getting multiple strings as form data, I see some extra output coming there and is not as expected, I wanted the output to be "Hi RAVI"

Is it good practice to require named parameters for data models in flutter when you know that the data should always have a specific field like an id or username? I think this would remove unnecessary null checking, but I've always seen model classes just use named parameters with fromJson and toJson methods especially if the data is being pulled from a database like Firebase. So is there a reason not to require fields?
Also when would it be a good idea to require a String field and initially populate it with an empty String vs making it nullable and initializing it with a null value?
Below is my opinion, i'm not sure it's true for all but it works for me
Reason 1: it's too long and unnecessary to write the whole thing out, some Jsons can be very complicated to do this, moreover when you get the data in JSON you'll want to simply initialize var A = A.fromJson(jsonData) instead of having to pass it one by one into the Model, moreover this can be repeated many times.
Reason 2: String with null(String?) and String with empty value(String) is very different. With me, I use String? to determine that "it has not received value yet", if the value is non-null then it has received a value including empty. In contrast to a String whose initial value is empty, I cannot distinguish whether it has received empty or has not received data.
Example: when i assign empty value to text2, it cannot distinguish whether it received the value before. This can be used to calculate the display of the Indicators before the variable actually gets a value.
I'm making a report in Data Studio using my Analytics data, and I'm having some trouble finding out how to filter it. Here is what I need to do:
I receive a "user" parameter in the URL, and I need to filter my "username" dimension with it. I want to make some kind of filter in the report, like Include usernameDimension = userParameter.
For some limitation in DataStudio, currently it is not possible to directly use Report URL parameters for filtering reports (when you create a filter, it only allows you to select fields, not parameters). However, it is possible to 'hack' this limitation with a new field that references the parameter.
Create a new boolean field called my_filter (or something you wish) with this expression:
field_i_want_to_filter = my_parameter
Then, just create a new filter in your report using this field, with the condition my_filter is true.
I can create a custom field to extract the username using a regular expressions.
Suppose you have a field called URL that contains something like:
https://example.com/path/path/endpoint?param1=blah¶m2=bleh&username=Diego¶m3=blih
You can use this formula in a new field to extract the username:
REGEXP_EXTRACT(URL, "[?&]username=([^&]*)")
You can easily add this custom field to a Drop down selector or something to allow filtering in your dashboard.
I have data stored in a database with short field names to save space. When I load these into my .NET Core app, I convert the data to its C# model. Then, when I pass this to the fronted I want to serialize the JSON to have full field names. So instead of "fN", "firstName".
I know I can use [JsonProperty(PropertyName = "SomeName")] to change serialization/deserialization. What I'm asking is whether there's a way to specify multiple property names for a single field, ideally with some additional "profile" variable so that when I serialize/deserialize from the DB I use the DB profile, and when sending to the client I use the other profile. This way I can either use the short or long names when convenient.
Thanks!
I have an HTML textbox where a user types some text and then the entries matching the text are retrieved from the database. I store this filter string value in a static string variable because I need to use its value somewhere in the program.
the question is: will all users currently logged in end up with the same filter result and overwrite their own filters every time they do a change.
I have a form with its method being "get" that passes the variables and their values to the query string, respectively. However, it also passes the viewstate variable in the query string. Now, I have a very long viewstate value on the given page, and if passed in the query string, the viewstate variable will cause the page to error out, due to "too long of a query string" which happens to also be too long of a url.
I cannot merely remove the viewstate variable - I need it. But I need to pass the viewstate variable along via some method other than get when the form is submitted, while the other inputs of the form (the non-hidden inputs) are appended to the query string. Is there any way to accomplish this?
Can you change the method to "post" and then use request.form to get your variables?
Otherwise, you might be able to use the session object...
...or a serializable class object
...or a temp table in a database
Several different options
