yes add inferAdditionalFields plugin to the authClient 
import { inferAdditionalFields } from "better-auth/client/plugins";
import { createAuthClient } from "better-auth/react";
import type { auth } from "./auth";

export const authClient = createAuthClient({
  plugins: [
    inferAdditionalFields<typeof auth>(),
  ],
});
import { inferAdditionalFields } from "better-auth/client/plugins";
import { createAuthClient } from "better-auth/react";
import type { auth } from "./auth";

export const authClient = createAuthClient({
  plugins: [
    inferAdditionalFields<typeof auth>(),
  ],
});

this one is there in the type system, but not there in the runtime if i add that code it works in the type system, but when i look for it in the runtime the useSession hook does not return that value from the user

that's not correct, they exists in the runtime. make sure you are on the latest version and did the database migration. if it doesn't work consider opening an issue on github.

i got it working. it was the database migration all along :/ however i found a bug that i will raise an issue later today or tomrrow.. when using sqlite and adding additionalfields as boolean wirth a defaultValue of false, it was setting it to true weirdly enough

check the migrations files and see if the filed is set to DEFAULT FALSE or not if its not present please post on github issues. consider marking this as done or solved
