RestoreAsync class abstract

An asynchronous utility class for decompressing data that was compressed using the Shrink class.

Uses compute to offload decompression to an isolate for UI performance. Always returns the same output as Restore.* but wrapped in a Future.

Example:

final decompressedText = await RestoreAsync.text(compressedTextBytes);
final decompressedJson = await RestoreAsync.json(compressedJsonBytes);

This class provides static methods corresponding to the compression methods in ShrinkAsync, allowing restoration of data in separate isolates to avoid blocking the UI.

Always restores data compressed by the corresponding ShrinkAsync.* methods.

Static Methods

bytes(Uint8List compressed) → Future<Uint8List>

Asynchronously decompresses a Uint8List that was compressed using Shrink.bytes.

json(Uint8List compressed) → Future<Map<String, dynamic>>

Asynchronously decompresses a Uint8List that was compressed using Shrink.json and converts it back to a JSON object in a separate isolate.

text(Uint8List compressed) → Future<String>

Asynchronously decompresses a Uint8List that was compressed using Shrink.text and converts it back to a string in a separate isolate.

unique(Uint8List compressed) → Future<List<int>>

Asynchronously decompresses a Uint8List that was compressed using Shrink.unique and converts it back to a list of unique integers in a separate isolate.
