Nativescript imagepicker .getImage() is not a function error - nativescript

Question

I have been trying to implement the answer to this question but keep getting the error "selected.getImage is not a function".
I have tried multiple different code examples at this point and I'm stumped. It seems like this is a type error, but I'm not sure where I can correct this.
I am looking to select a single image and return the path to that image in order to upload to the server. I don't need to display it on the device, though that is an option I suppose. Seems easy enough, but apparently I'm missing something.
I'm using v. 6.0.1 or the imagepicker plugin. I'd quote the code, but at this point I am using the exact example provided by Shiva Prasad in the above question.
Adding code per Max Vollmer:
var context = imagepickerModule.create({
mode: "single" // allow choosing single image
});
context
.authorize()
.then(function () {
return context.present();
})
.then(function (selection) {
console.log("Selection done:");
setTimeout(() => {
selection.forEach(function (selected) {
selected.getImage().then((source) => {
console.log(selected.fileUri); // this is the uri you need
});
});
}, 1000);
}).catch(function (e) {
console.log(e);
});

Answer 1

I was facing the exact same error yesterday.
I use the fromAsset function directly on the "selected" because apparently with the new version of this plugin, "selected" is an Asset. So you got an imageSource and you can use the "saveToFile" function that will copy the Asset into a new location (get this location using fileSystemModule from TNS). Use the path of this new location for your UI, and the image will appear. You can also create a file object from this location fileSystemModule.File.fromPath(path);, I use for upload.
context
.authorize()
.then(function () {
return context.present();
})
.then(function (selection) {
selection.forEach(function (selected) {
let file;
if (selected._android) {
file = fileSystemModule.File.fromPath(selected._android);
//viewModel.uploadFile(file);
}else{
imageSourceModule.fromAsset(selected).then((imageSource) => {
const folder = fileSystemModule.knownFolders.documents().path;
const fileName = "Photo.png";
const path = fileSystemModule.path.join(folder, fileName);
const saved = imageSource.saveToFile(path, "png");
if (saved) {
console.log("Image saved successfully!");
file = fileSystemModule.File.fromPath(path);
//viewModel.uploadFile(file);
}else{
console.log("Error! - image couldnt save.");
}
});
}
});
}).catch(function (e) {
console.log(e);
// process error
});
Explanation
The uncommented snippet (//viewModel.uploadFile(file);), viewModel reference (will be different on your app) and the function: uploadFile for example is where you would pass the file to upload it or set it to the image.src etc
Make sure to declare imageSourceModule at the top.
const imageSourceModule = require("tns-core-modules/image-source");
