I've been trying to make it so that my program does not allow you to input more than a certain amount of characters into a TextInput component, similar to how maxLength works for input. I haven't been able to find anything similar maxLength for textInput. Is there an easy way to set a maximum number of characters for the < TextInput /> component?

Firstly Let's import React Native default TextInput to our code. Inside our component state we will define two properties value & height. value to hold our TextInput value & height to control our TextInput height.
numberOfLinesSets the number of lines for a TextInput . Use it with multiline set to true to be able to fill the lines.
Approach 1: Using maxLength: We will use maxLength attribute for our input. It is the same as the maxlength attribute used for HTML. It restricts the user to enter characters till it reaches the maxLength limit that we have set.
In the props for TextInput you can set a maxLength attribute.
From the documentation:
maxLength number
Limits the maximum number of characters that can be entered. Use this instead of implementing the logic in JS to avoid flicker. @platform ios
