Ionic native Base64 To Gallery doesn't work

Ionic Framework ionic-v3
1

Hello,

I’m trying to use the “Base64 To Gallery” plugin from Ionic native but it doesn’t work.

Base64ToGallery.base64ToGallery(base64Data, ‘img_’).then(
res => console.log("Saved image to gallery ", res),
err => console.log("Error saving image to gallery ", err)
);

I’m working on Ionic 2 TS and have this error :

Error TS2339: Property ‘base64ToGallery’ does not exist on type ‘typeof Base64ToGallery’

If someone already figure out this problem it will be nice to get some advices.

Best regards,
François

maybe there are missing typings for Base64ToGallery. Try this:

Base64ToGallery['base64ToGallery'](base64Data, 'img_').then(
  res => console.log("Saved image to gallery ", res),
  err => console.log("Error saving image to gallery ", err)
);

Thanks for the quick reply I really appreciate.

Unfortunately, there is another error :

EXCEPTION: TypeError: ionic_native_1.Base64ToGallery[‘base64ToGallery’] is not a function. (In ‘ionic_native_1.Base64ToGallery’base64ToGallery’’, ‘ionic_native_1.Base64ToGallery[‘base64ToGallery’]’ is undefined)

And you added the cordova plugin correctly to your app?
https://www.npmjs.com/package/cordova-base64-to-gallery

Yes I did.

I changed the following files like this and now it’s work.

base64togallery.js

“use strict”;
var __decorate = (this && this.__decorate) || function (decorators, target, key, desc) {
var c = arguments.length, r = c < 3 ? target : desc === null ? desc = Object.getOwnPropertyDescriptor(target, key) : desc, d;
if (typeof Reflect === “object” && typeof Reflect.decorate === “function”) r = Reflect.decorate(decorators, target, key, desc);
else for (var i = decorators.length - 1; i >= 0; i–) if (d = decorators[i]) r = (c < 3 ? d(r) : c > 3 ? d(target, key, r) : d(target, key)) || r;
return c > 3 && r && Object.defineProperty(target, key, r), r;
};
var plugin_1 = require(‘./plugin’);
/**

  • import {Base64ToGallery} from ‘ionic-native’;
  • Base64ToGallery.base64ToGallery(base64Data, ‘img_’).then(

var Base64ToGallery = (function () {
function Base64ToGallery() {
}
/*

* @param data
* @param prefix
*/
Base64ToGallery.base64ToGallery = function (data, prefix, mediaScanner) { return; };
__decorate([
plugin_1.Cordova()
], Base64ToGallery, “base64ToGallery”, null);
Base64ToGallery = __decorate([
plugin_1.Plugin({
plugin: ‘cordova-base64-to-gallery’,
pluginRef: ‘cordova’,
repo: ‘GitHub - Nexxa/cordova-base64-to-gallery: ⚠ this project is not longer maintained - Cordova plugin to save base64 data as a png image into the device’,
platforms: [‘Android’, ‘iOS’, ‘Windows Phone 8’]
})
], Base64ToGallery);
return Base64ToGallery;
}());
exports.Base64ToGallery = Base64ToGallery;
//# sourceMappingURL=base64togallery.js.map

and

base64togallery.d.ts

/**

  • err => console.log("Error saving image to gallery ", err)
  • );

/
export declare class Base64ToGallery {
/*
* Converts a base64 string to an image file in the device gallery
* @param data
* @param prefix
*/
static base64ToGallery(data: string, prefix?: string, mediaScanner?: boolean): Promise;
}

Thanks for your help.

If this is a general issue with the plugin --> create a pull request for the plugin, because hacking in plugin code is not the best solution ;).

This still doesn’t work without the modifications above. Has the change above been merged?

Hi, I am having also problem with above plugin.

I’ve installed plugin as described on here

Error i am getting is: “data.replace” is not a function.

It seems i don’t have content of base64togallery.js as above. But i found this
data.replace
within the code inside
plugins/cordova-base64-to-gallery/src/www/base64togallery.js
as well as
node_modules/cordova-base64-to-gallery/src/www/base64togallery.js
I’ve tried to change data.replace to data.result.split(',')[1] in both fies.
Than i ran:
ionic cordova run android
Unfortunatelly i am getting same error, not sure why it did not include my changes.
Any help much appreciated.

Thanks

Ok so in my case it was simply need of adding permissions to the page constructor which was trying to save image into gallery. Code below solved it:

this.androidPermissions.checkPermission(this.androidPermissions.PERMISSION.WRITE_EXTERNAL_STORAGE).then(
      result => console.log("Permissions granted", result.hasPermissions),
      error => this.androidPermissions.requestPermission(this.androidPermissions.PERMISSION.WRITE_EXTERNAL_STORAGE)
    );
    this.androidPermissions.requestPermissions([this.androidPermissions.PERMISSION.WRITE_EXTERNAL_STORAGE]);
