Blobwrapper.The wrapper works for the targeted MIME types. Two details deserve a check.
The regex on Line 18 is case-sensitive, but media types are case-insensitive. A blob with type
Text/JavaScriptortext/JavaScriptdoes not get the charset. Add theiflag. The existing^...$anchors already skip types that carry parameters, such as;charset=..., so a charset the SDK sets is not overridden.
Utf8Blobis a plain function. It does not copy static members ofBlob.Blobhas none that matter today.Utf8Blob.prototype = OriginalBlob.prototypealso leavesblob.constructorpointing atOriginalBlob. This is harmless for the Dart/Flutter SDK, so no change is needed. Do not rely oninstanceof Utf8Blobanywhere.Proposed fix for the case-insensitive match
- /^(text|application)\/(java|ecma)script$/.test(options.type) + /^(text|application)\/(java|ecma)script$/i.test(options.type)Based on learnings: HTTP header names and media types are case-insensitive, so the case-sensitive regex comparison should be normalized.
