I'm trying to migrate from the deprecated putValueArgument in IrMemberAccessExpression and need some guidance.

There is this brief doc in the source file:

"Sets one of arguments that correspond to IrParameterKind.Context or IrParameterKind.Regular parameters.
This is, index corresponds to IrFunction.valueParameters list, and not IrFunction.parameters, which also includes receiver parameters.
This is a deprecated API!
Use arguments instead.
E.g. for code
call.putValueArgument(parameter.indexInOldValueParameters, ...)
the replacement should be
call.arguments[parameter.indexInParameters] = ...
If you need to know the IrParameterKind of the arguments, reach out to the corresponding function's parameter.
Details on the API migration: KT-68003"

Say I want to migrate:

putValueArgument(0, expr)

I'm not clear on how to get "parameter.indexInParameters" in this case.

And where can I find "the API migration: KT-68003"?

Any help please.

Hi, the migration doc is here.
For your question about putValueArgument, the kdoc assumes you have an instance of IrValueParameter and you want to set an argument that corresponds to it. But if you just specify the index as a constant, you can still do so with call.arguments[N] = expr . Please only note that this constant index may now be different, e.g. 1 instead of 0, because you now also have to count receivers and context parameters, if any. More on that in the guide I linked.
