uri_content 2.0.0 uri_content: ^2.0.0 copied to clipboard
Get the Uint8List content of a given Uri. Supports file, data, content and http/https
uri_content
allows you to fetch the content of a URI without creating any temporary files during the process. You don't need to worry about any garbage being left behind.
It supports the following schemes: file
, data
, http/https
, content
(Android only)
Getting Started #
import 'package:uri_content/uri_content.dart';
Using getContent()
function #
Future<void> getReadmeContent() async {
try {
final uri = Uri.parse(
"https://raw.githubusercontent.com/talesbarreto/pull_request_coverage/main/README.md",
);
print(await (uri.getContent().then(utf8.decode)));
} catch (e, s) {
print("An error happened $e\n$s");
}
}
UriContent
instance #
UriContent
is preferred because it offers additional options such as custom HTTP headers and the ability to adjust the default buffer size for content schemes. It also facilitates code testing since you can mock its instance.
final uriContent = UriContent();
Future<void> getReadmeLength() async {
try {
final content = await uriContent.from(Uri.parse(
"https://raw.githubusercontent.com/talesbarreto/pull_request_coverage/main/README.md",
));
print("Content length is ${content.length}");
} catch (e, s) {
print("An error happened $e\n$s");
}
}
Methods available: #
Stream<Uint8List> getContentStream(Uri uri)
: Retrieves a Stream of Uint8List where each event represents a chunk of content from the specified URI. This approach is more suitable when you don't need the entire content at once, such as in a request provider or when directly saving the bytes into a File. Handling small chunks significantly reduces memory consumption.Future<Uint8List> from(Uri uri)
: Retrieves the entire content at once. Be cautious as it may crash your app when attempting to retrieve a large file.Future<Uint8List?> fromOrNull(Uri uri)
: Same asfrom
, but returns null instead of throwing an exception when an error happensFuture<bool> canFetchContent(Uri uri)
: Check if the content is reachable and supported.
The function getContentOrNull()
is also available if you are not interested in handling errors.
