Differentiation of function has a method to solve, by limits
$$ \frac{d(f(x))}{dx} = \lim_{h\to 0}\frac{f(x+h)-f(x)}{h}$$
Is there any method by which we can solve integral without using antiderivative, like differentiation does?

The short answer is "no". There is no mechanical way to integrate generally. Additionally, you will find that there are a lot of "basic" integrals that have no symbolic solutions. (Note that, technically, anything has a symbolic solution if you simply define a new symbol. However, integration doesn't have any closed set like differentiation does.)
Example: $\int \cos(x^2)\,dx$ does not have a solution, except by introducing a new symbol to represent its results (and, in fact, the "fresnel integral" function is often used for that one).
In mathematics, not everything can be mechanically determined. This comes as a surprise to many, but it is a fact of mathematics.
