Ionic Save large file @Capacitor/filesystem - Out of memory error

Question

I try to store multiple files in the file storage by using the @Capacitor/filesystem Plugin.

On large files I'm facing the following error - testet on my One Plus Pro 8 (Android 12):

W/System.err: java.lang.OutOfMemoryError: Failed to allocate a 150994952 byte allocation with 25165824 free bytes and 140MB until OOM, target footprint 280973616, growth limit 402653184

Code for saving the files:

Filesystem.writeFile({
        path,
        data: file.base64,
        directory: Directory.Data,
        recursive: true
      })

Project configuration:

Answer 1

Saving large files is currently not supported (see https://github.com/ionic-team/capacitor/issues/984 ).

The Capacitor team has communicated on Discord that there are plans to add support with Capacitor 4.

Answer 2

I found the following package wich solved my problem:

Capacitor-blob-writer

It splits the file into multiple parts if it's to low.
