Question

Here is my function in flutter
I have use multi_image_picker to pick images sand i have save them in that variable images. Now I want post those images in laravel api. But this don't work.
if(images != null ){
try{
List<MultipartFile> allMultiFiles = [];
for (Asset asset in images) {
ByteData byteData = await asset.getByteData();
List<int> imageData = byteData.buffer.asUint8List();
print(imageData);
var multipartFile = new MultipartFile.fromBytes(
imageData,
filename: asset.name,
);
allMultiFiles.add(multipartFile);
}
FormData formData = FormData.fromMap({
'images' : allMultiFiles
});
var response = await dio.post(UPLOAD_URL, data:formData);
if(response.statusCode == 200){
print('done');
}else{
print('not save image. Error !!');
}
}catch (e){
print(e.toString());
}
}
}
Here is my function to store
public function save(Request $request){
if(!$request->hasFile('images')){
return response()->json([
'upload file not found' => 'not found'
],400);
}else{
$allowedExtension = ['jpg','jpeg','png'];
$files = $request->file('images');
$erros = [];
foreach ($files as $file){
$extension = $file->getClientOriginalExtension();
$check = in_array($extension,$allowedExtension);
if($check) {
foreach($request->images as $mediaFiles) {
$path = $mediaFiles->store('public/images');
$name = $mediaFiles->getClientOriginalName();
return response()->json([
'message' => 'images saved'
],200);
}
} else {
return response()->json(['invalid_file_format'], 422);
}
}
}
}
