BlossomRepositoryImpl class
Methods
-
checkBlob({required String sha256, required List<String> serverUrls, Nip01Event? authorization})
→ Future<String>
-
Checks if the blob exists on the server
If
authorization is null, the server must be public
override
-
computeFileHash(String filePath)
→ Stream<FileHashProgress>
-
Computes SHA256 hash of a file by reading it in chunks
Returns stream updates with progress and a final event containing FileHashProgress.hash
override
-
deleteBlob({required String sha256, required List<String> serverUrls, required Nip01Event authorization})
→ Future<List<BlobDeleteResult>>
-
Attempts to delete blob from all servers
override
-
directDownload({required Uri url})
→ Future<BlobResponse>
-
Directly downloads a blob from the url, without blossom
override
-
directDownloadToFile({required Uri url, required String outputPath})
→ Future<void>
-
Directly downloads a blob from the url to a file, without blossom
override
-
downloadBlobToFile({required String sha256, required String outputPath, required List<String> serverUrls, Nip01Event? authorization})
→ Future<void>
-
Downloads a blob directly to a file path
For web: triggers browser download dialog with the file
For native: saves to the file system at the given path
override
-
getBlob({required String sha256, required List<String> serverUrls, Nip01Event? authorization, int? start, int? end})
→ Future<BlobResponse>
-
Gets a blob by trying servers sequentially until success
If
authorization is null, the server must be public
If start and end are null, the entire blob is returned
start and end are used to download a range of bytes, @see MDN HTTP range requests
override
-
getBlobStream({required String sha256, required List<String> serverUrls, Nip01Event? authorization, int chunkSize = 1024 * 1024})
→ Future<Stream<BlobResponse>>
-
checks if the server supports range requests, if no server supports range requests, the entire blob is returned
otherwise, the blob is returned in chunks. @see MDN HTTP range requests
override
-
listBlobs({required String pubkey, required List<String> serverUrls, DateTime? since, DateTime? until, Nip01Event? authorization})
→ Future<List<BlobDescriptor>>
-
Lists blobs from the first successful server
override
-
mirrorToServer({required String fileUrl, required String serverUrl, required String sha256, required Nip01Event authorization})
→ Future<BlobUploadResult>
-
Mirror a file from one server to another, based on the file URL
override
-
noSuchMethod(Invocation invocation)
→ dynamic
-
Invoked when a nonexistent method or property is accessed.
inherited
-
report({required String serverUrl, required String sha256, required Nip01Event reportEvent})
→ Future<int>
-
Reports a blob to the server
sha256 is the hash of the blob
reportEvent is the report event
override
-
supportsRangeRequests({required String sha256, required String serverUrl})
→ Future<Tuple<bool, int?>>
-
first value is whether the server supports range requests
second value is the content length of the blob in bytes
override
-
toString()
→ String
-
A string representation of this object.
inherited
-
uploadBlob({required Stream<List<int>> dataStreamFactory(), required int contentLength, required Nip01Event authorization, String? contentType, required List<String> serverUrls, UploadStrategy strategy = UploadStrategy.mirrorAfterSuccess, bool mediaOptimisation = false})
→ Stream<BlobUploadProgress>
-
Uploads a blob using the specified strategy
Returns a stream of progress updates
override
-
uploadBlobFromFile({required String filePath, required Nip01Event authorization, String? contentType, required List<String> serverUrls, UploadStrategy strategy = UploadStrategy.mirrorAfterSuccess, bool mediaOptimisation = false})
→ Stream<BlobUploadProgress>
-
Uploads a blob from a file path using the specified strategy
Reads the file in chunks to minimize memory usage
For web: prompts user to select a file via File System Access API
For native: filePath is the actual file system path
Returns a stream of progress updates
