What is the point of exploitation in reinforcement learning? Why can't we only do exploration?

I just started learning about RL, and I've tried researching and reading about this question, but I couldn't seem to find a definitive answer. The best answer that I could formulate from what I've read is (sorry if some of my vocabulary is incorrect):

(In the context of Q-learning) Overly exploring can cause the agent to not explore some state action pairs, due to the small chance of achieving certain states with random actions, causing the model to take longer to achieve convergence in those rare states. Overly exploiting can cause the agent to never explore some states and actions that are deemed non-optimal given current Q-value estimates, even if they are actually optimal.

Would this be correct, or is there even more to it? If this is the case, why do we want to exploit more as time goes on (such as in the decaying epsilon-greedy strategy)?

Try below code hope its helpful to you. add your ListView() inside Padding

    Padding(
          padding: EdgeInsets.all(20),
          child: ListView(
            children: <Widget>[
              SizedBox(
                child: TextField(
                  autofocus: true,
                  onChanged: (val) {},
                  decoration: InputDecoration(
                    contentPadding: const EdgeInsets.all(10.0),
                    labelText: 'Employee Name',
                    hintText: 'widget.user.name',
                    labelStyle: const TextStyle(
                      color: Color.fromARGB(255, 107, 106, 144),
                      fontSize: 14,
                      fontWeight: FontWeight.w500,
                    ),
                    border: OutlineInputBorder(
                      borderSide: const BorderSide(
                          color: Color.fromARGB(255, 107, 106, 144),
                          width: 2),
                      borderRadius: BorderRadius.circular(10),
                    ),
                  ),
                ),
                width: 150.0,
              ),
              SizedBox(
                height: 20,
              ),
              SizedBox(
                child: TextField(
                  autofocus: true,
                  onChanged: (val) {},
                  decoration: InputDecoration(
                    contentPadding: const EdgeInsets.all(10.0),
                    labelText: 'Employee Email',
                    hintText: 'widget.user.email',
                    labelStyle: const TextStyle(
                      color: Color.fromARGB(255, 107, 106, 144),
                      fontSize: 14,
                      fontWeight: FontWeight.w500,

                    border: OutlineInputBorder(
                      borderSide: const BorderSide(
                          color: Color.fromARGB(255, 107, 106, 144),
                          width: 2),
                      borderRadius: BorderRadius.circular(10),
                    ),
                  ),
                ),
                width: 150.0,
              ),
              TextButton(
                onPressed: () {},
                child: const Text('Save'),
