Solve \begin {gather*} \boxed {y^{\prime }-y^{2} f \relax (x )+f \relax (x ) \left ({\mathrm e}^{\lambda x} a +b \right ) y-a \lambda \,{\mathrm e}^{\lambda x}=0} \end {gather*}

Solution by Maple

dsolve(diff(y(x),x)=f(x)*y(x)^2-f(x)*(a*exp(lambda*x)+b)*y(x)+a*lambda*exp(lambda*x),y(x), singsol=all)
