How to generate Query Classes with direct values in Constructor not as an Optional Types ?

[RageshAntony]

Question

Enter your question here.

Apollo KMM is generating Query Classes as Optional Types ..

public data class LoginUserQuery(
  public val phone_no: Optional<String?> = Optional.Absent,
  public val password: Optional<String?> = Optional.Absent,
.....

This makes me to call the constructor like LoginUserQuery(phone_no = Optional.presentIfNotNull("999999"),password = Optional.presentIfNotNull("ddd"))

I need something like

    LoginUserQuery(phone_no = "999999",password = "ddd")

Is there any configuration to generate like above ?

Hi!

If you declare your variables as non nullable (with !) they won't be generated as optional. Something like:

query LoginUserQuery($phone_no: String!, $password: String!) {

Yeah. Working Now. Thanks .

But is there any way to do the same for nullable , like generating classes with default value constructs ..

public data class LoginUserQuery( public val phone_no: String? = null, public val password: String, )

like this ?

[BoD]

You can define a default value on query arguments, like this:

query LoginUserQuery($phone_no: String = null, $password: String!) {

this will generate something like:

public data class LoginUserQuery(
  public val phone_no: Optional<String?> = Optional.Absent,
  public val password: String,
)

Note, the reason Optional is generated by default is because a backend may distinguish:

• no value
• a present value which is null

If that's preferable, your can configure Apollo to generate a nullable type instead, by either adding @optional(if: false) on a specific argument, or globally with generateOptionalOperationVariables.set(false) - more info about this here. But note that if you use a default value as above, it will still be generated with Optional.

@BoD .. Wow. This is what I expected. Thanks
