Flutter – When i don't give the optional suffixIcon to my customTextField the hintText also not visible

To ensure that the hintText is visible even when no suffixIcon is provided in your custom TextField, you need to ensure that the layout and styling of your custom TextField widget are configured correctly. Here’s a step-by-step guide to achieve this:

1. Check the contentPadding property: Make sure that the contentPadding property of your custom TextField is appropriately set to provide enough space for both the text input and the hint text. This padding ensures that the hint text is not obscured by the input text or any other widget.

2. Verify the prefixIcon and suffixIcon properties: If your custom TextField widget expects prefixIcon and suffixIcon but you don’t want to provide a suffixIcon, ensure that your widget implementation can handle this case gracefully. It should not affect the visibility of the hint text.

3. Inspect the widget’s build method: Review the build method of your custom TextField widget to ensure that it properly handles the absence of a suffixIcon. Ensure that the suffixIcon is conditionally included in the widget’s layout, and that the hint text is always visible regardless of whether a suffixIcon is provided.

Here’s a simplified example demonstrating how you can implement a custom TextField widget that ensures the hint text is always visible, even without a suffixIcon:

import 'package:flutter/material.dart';

class CustomTextField extends StatelessWidget {
  final String hintText;
  final Widget? suffixIcon;

  const CustomTextField({
    Key? key,
    required this.hintText,
    this.suffixIcon,
  }) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return TextField(
      decoration: InputDecoration(
        hintText: hintText,
        suffixIcon: suffixIcon,
        contentPadding: EdgeInsets.symmetric(vertical: 12.0, horizontal: 16.0),
      ),
    );
  }
}

In this example, the CustomTextField widget accepts a hintText and an optional suffixIcon. It ensures that the hint text is always visible by setting appropriate contentPadding. The suffixIcon is included conditionally based on whether it’s provided, but its absence does not affect the visibility of the hint text.

Ensure that your implementation aligns with these principles, and adjust your custom TextField widget accordingly. If the issue persists, you may need to provide more details or code for further assistance.
