SelectImage | Android -- 选择多张图片，支持拖拽删除、排序、预览图片

I used two circular avatar (the first one with a white background just a little bigger to create a white border). Also the second one have the background property set to white. However before the image is loaded I see a blue background. As you can see form the code there are no one blu widget on the back... I wold like to have a black or white background while the widget is loading the picture.

I am trying to save image in sqlite database using flutter below is my helper class where i want to save data

I have an array of files for appending them in form data later, but first i need to compress them and append in new array of already compressed files. I'm stuck with appending files to new array in loop.

I am trying to allow select multiple images in my android application which works fine but for some reasons i am not able to get the data of the images selected in the activity result. The clipData seems to be empty when i select multiple images but the data works fine when i select a single image. Here is the code i currently have.

I am getting the following error while expecting the method buildSplashScreen() to return image:

This is my code below:

I am creating a react Native IOS app and have mostly followed this tutorial with a few changes. The app should function by picking an image from your library, the image is displayed, you press upload image and the progress bar tracks upload progress which when completed will give you an alert that the photo has been uploaded to firebase.

I have managed to get to the point where all explained above is working as it should, except after checking if the photo has been uploaded... it hasn't.

This is my file setup:

This is my UploadScreen.js file:
