get_storage_info

A Flutter plugin to get information about storage on Android. Get free, used, and total internal and external (SD card) storage space, and more.

This is a friendly fork of storage_info with additional useful methods and improvements.

Installing

Add get_storage_info to your pubspec.yaml:

dependencies:
  get_storage_info: ^0.3.0

Usage

Importing

import 'package:get_storage_info/get_storage_info.dart';

Using the methods

All methods can be statically accessed via the GetStorageInfo class.

Get internal storage info

// Get internal storage total space in bytes, MB and GB
await GetStorageInfo.getStorageTotalSpace; // return int
await GetStorageInfo.getStorageTotalSpaceInMB; // return double
await GetStorageInfo.getStorageTotalSpaceInGB; // return double

// Get internal storage free space in bytes, MB and GB
await GetStorageInfo.getStorageFreeSpace; // return int
await GetStorageInfo.getStorageFreeSpaceInMB; // return double
await GetStorageInfo.getStorageFreeSpaceInGB; // return double

// Get internal storage used space in bytes, MB and GB
await GetStorageInfo.getStorageUsedSpace; // return int
await GetStorageInfo.getStorageUsedSpaceInMB; // return double
await GetStorageInfo.getStorageUsedSpaceInGB; // return double

Get external (SD card) storage info

// Get external storage total space in bytes, MB, and GB
return await GetStorageInfo.getExternalStorageTotalSpace; // return int
return await GetStorageInfo.getExternalStorageTotalSpaceInMB; // return double
return await GetStorageInfo.getExternalStorageTotalSpaceInGB; // return double

// Get external storage free space in bytes, MB, and GB
return await GetStorageInfo.getExternalStorageFreeSpace; // return int
return await GetStorageInfo.getExternalStorageFreeSpaceInMB; // return double
return await GetStorageInfo.getExternalStorageFreeSpaceInGB; // return double

// Get external storage used space in bytes, MB, and GB
return await GetStorageInfo.getExternalStorageUsedSpace; // return int
return await GetStorageInfo.getExternalStorageUsedSpaceInMB; // return double
return await GetStorageInfo.getExternalStorageUsedSpaceInGB; // return double

Get whether the external storage is mounted and writable

bool isWritable = await GetStorageInfo.isExternalStorageWritable; // return bool
>> true

Get the size of a given directory in MB

String directoryPath = '/storage/emulated/0/Movies/MyFolder/';
double directorySize = await GetStorageInfo.getSizeOfDirectoryInMB(directoryPath);
>> 12.98790

Get storage type from path

String path = '/storage/emulated/0/Android';
DeviceStorageType storageType = GetStorageInfo.getStorageTypeFromPath(path);
>> DeviceStorageType.internal

Get storage usage value

Get a value from 0.0 to 1.0 representing the storage usage. Useful for storage indicators.

double storageTotal = await GetStorageInfo.getExternalStorageTotalSpaceInGB;
double storageUsed = await GetStorageInfo.getExternalStorageUsedSpaceInGB;

double storageUsageValue = GetStorageInfo.getStorageUsageValue(storageUsed, storageTotal);
>> 0.95

Get whether the storage type is low on storage

This method calls the above methods internally to get the storage info, so if you already get the info in your code it may be more optimized to use getIsStorageBelowThreshold instead.

DeviceStorageType storageType = DeviceStorageType.internal;

// Optionally set the threshold. The default is 500MB.
double threshold = 600.0;

bool isLowOnStorage = await GetStorageInfo.getIsLowOnStorage(storageType, threshold);
>> false

Get whether the storage is below the low storage threshold

double threshold = 600.0; // in MB
double storageFree = await GetStorageInfo.getExternalStorageFreeSpaceInMB;

bool isBelowThreshold = GetStorageInfo.getIsStorageBelowThreshold(storageFree, threshold);
>> true
