I want to get an image path from selected multiple images, I’m using this link to select multiple images but I got assets, I want paths from selected multiple images because I want to upload into the API.
I added this dependency in pubspec.yaml
If there any good way to do this, please tell me
multi_image_picker: ^4.6.3
This is my file upload class, This UI looks similar to Facebook.

You can also select multiple images using file_picker: ^1.5.0+2 library and easy to get path of selected images
}
I’m Using below Code to select multiple images by using file_picker: ^2.0.7 Library.
Long press to select multiple image. Once Image Selected you can use f arr to display the images.
Sample API Call For image upload and normal data. Image uploaded column should be arr ( photo[] ).
Use multi_image_picker 4.7.14 library to pick Multiple Images. use below code you can send selected asset image as a file. `
API Call : while image uploading place use multipart file
