services.AddFlareHttpClient(new FlareApiClientOptions
{

});

Then inject IFlareApiClient:

public class MyService
{
    private readonly IFlareApiClient _client;

    public MyService(IFlareApiClient client) => _client = client;

    public async Task<bool> IsFlagEnabled(string flagKey)
    {
        var context = new FlareEvaluationContext
        {
            Scope = "production",
            TargetingKey = "user-123"
        };

        var result = await _client.EvaluateAsync(flagKey, context);
        return result.Value;
    }

    public async Task<IReadOnlyList<FlagEvaluationResponse>> GetAllFlags()
    {
        var context = new FlareEvaluationContext { Scope = "production" };
        var result = await _client.EvaluateAllAsync(context);
        return result.Flags;
    }
}
