Question 1

How do I add custom validation rules in React Native Form Generator?

Accepted Answer

Use the validationFunction prop on fields like InputField, which accepts a single function or array of functions that return true for valid or a string for errors, as shown in the example with multiple validators.

Question 2

Can I use React Native Form Generator with TypeScript?

Accepted Answer

Yes, it should work since it's a JavaScript library, but type definitions aren't provided out-of-the-box, so you might need to create your own or find community contributions for full TypeScript support.

Question 3

React Native Form Generator vs Formik: which is better for forms?

Accepted Answer

React Native Form Generator focuses on native UI components and automatic event handling, while Formik is more abstract and works with any UI library. Choose based on whether you prioritize native look and feel (Form Generator) or flexible state management (Formik).

Question 4

How to style form fields to match my app's design?

Accepted Answer

Override default styles using props like placeholderStyle and valueStyle, or create custom field components as described in the 'Wrapping fields' section, allowing full control over appearance.

Question 5

Does it support dynamic form fields or conditional rendering?

Accepted Answer

Yes, since it's built with React, you can conditionally render fields based on state, and the form data updates dynamically via the onChange event, though you need to manage logic yourself.

Question 6

How to handle keyboard events and scrolling in forms?

Accepted Answer

The library includes a KeyboardAwareScrollView implementation, as mentioned in the 'KeyboardEvents' section, which automatically adjusts for keyboard visibility to prevent input overlap.
