| /** |
| * @assertion Uri.dataFromString( |
| * String content, { |
| * String mimeType, |
| * Encoding encoding, |
| * Map<String, String> parameters, |
| * bool base64: false |
| * }) |
| * Creates a data: URI containing the content string. |
| * |
| * Converts the content to a bytes using encoding or the charset specified in |
| * parameters (defaulting to US-ASCII if not specified or unrecognized), then |
| * encodes the bytes into the resulting data URI. |
| * |
| * Defaults to encoding using percent-encoding (any non-ASCII or non-URI-valid |
| * bytes is replaced by a percent encoding). If base64 is true, the bytes are |
| * instead encoded using BASE64. |
| * |
| * If encoding is not provided and parameters has a charset entry, that name is |
| * looked up using Encoding.getByName, and if the lookup returns an encoding, |
| * that encoding is used to convert content to bytes. If providing both an |
| * encoding and a charset parameter, they should agree, otherwise decoding |
| * won't be able to use the charset parameter to determine the encoding. |
| * |
| * If mimeType and/or parameters are supplied, they are added to the created |
| * URI. If any of these contain characters that are not allowed in the data URI, |
| * the character is percent-escaped. If the character is non-ASCII, it is first |
| * UTF-8 encoded and then the bytes are percent encoded. An omitted mimeType in |
| * a data URI means text/plain, just as an omitted charset parameter defaults to |
| * meaning US-ASCII. |
| * @description Checks that this constructor creates an expected Uri. Test |
| * base64 parameter specified |
