I want to add text after image on product list page. For that I created plugin for getImage() function of vendor/magento/module-catalog/Block/Product/AbstractProduct.php

Plugin Code:

<?php

namespace Vendor\Module\Model;

class Product extends \Magento\Catalog\Block\Product\AbstractProduct
{
    public function afterGetImage(\Magento\Catalog\Model\Product $subject, $result)
    {
        $result .= 'Testing From Plugin';
        return $result;
    }
}

But I'm getting this error:

Uncaught TypeError: Argument 2 passed to Magento\Catalog\Block\Product\AbstractProduct::__construct() must be of the type array, object given

What I am doing wrong?

It create an Issue because return type of getImage is \Magento\Catalog\Block\Product\Image and you are trying to convert into string. I think by just appending the text you can not achieve your goal.

I am not sure what is your exact goal but I can assume that you need to add additional attribute to product Image attribute so you can use it in your phtml file. For that you can print the $result->getData() in your log file you can see that number of product Image attribute. So you can add your custom attribute by appending this data.

In log file I am getting,

array (
  'image_url' => 'My Product image URL,
  'width' => '240',
  'height' => '300',
  'label' => 'test',
  'ratio' => 1.25,
  'custom_attributes' => '',
  'resized_image_width' => 135,
  'resized_image_height' => 135,
  )

You can use with aroundPlugin and check,

 public function aroundGetImage(
            \Magento\Catalog\Block\Product\AbstractProduct $subject,
            \Closure $proceed,
            \Magento\Catalog\Model\Product $product,
            $imageId,
            $attributes = []
        ) {
            $result = $proceed($product, $imageId, $attributes);
            $newStr = 'Testing From Plugin';
            return $result. $newStr;
        }
