loadNetworkSvg static method
Loads an SVG from a network URL and returns a SvgData
object. The SVG is
loaded asynchronously, and the returned Future is completed with the
SvgData
object when the SVG is fully loaded. If cacheId
is provided,
the loaded SVG will be added to the SVG cache using cacheId
as the key.
Throws a FlutterError if the SVG cannot be loaded.
Implementation
static Future<SvgData> loadNetworkSvg(
String url, {
String? cacheId,
NetworkEventCallback? onComplete,
NetworkEventCallback? onProgress,
NetworkEventCallback? onError,
}) async {
final response = await NetworkImageLoader.loadSvg(
url,
onComplete: onComplete,
onProgress: onProgress,
onError: onError,
);
if (response.isError) {
throw FlutterError(
'Unable to load SVG $url.\nReason: ${response.reasonPhrase}');
}
if (response.isSvg && cacheId != null) {
svgCache[cacheId] = response.svgData!;
}
return response.svgData!;
}
