@ADLsourceCode thanks for quick response.

How do you build your project? Do you use configured web compilers (https://github.com/dart-lang/build/blob/master/build_web_compilers/README.md#configuring-the-sound-null-safety-mode)?

Hi @bednar ,
I just made a new project with Flutter 2 and used the Influx package and the code from Github. I use the general build with
sound_null_safety: true , it gave the above error and when I used sound_null_safety: false, it ran but querying my DB gives me another error which I mentioned on a different ticket here #14

@ADLsourceCode thanks for detail info, @rhajek will take a look

Unfortunately, we generate apis from swagger using openapi-generator that still does not support null safety,
OpenAPITools/openapi-generator#8278

[ADLsourceCode]

What do you suggest me to do in order to solve this problem?

As a temporary workaround you can disable sound null safety.
I tested a newly created project with Flutter 2.5.2 + influxdb_client (git main branch), flutter run --no-sound-null-safety works form me.
