uri property Null safety
Points to a Cloud Storage URI containing file(s) to import.
The URI must be in the following format:
The URI can include wildcards in
object_id and thus identify multiple
files. Supported wildcards: *
* to match 0 or more non-separator
** to match 0 or more characters (including separators).
Must be used at the end of a path and with no other wildcards in the path.
Can also be used with a file extension (such as .ndjson), which imports
all files with the extension in the specified directory and its
sub-directories. For example,
gs://my-bucket/my-directory / * *.ndjson
imports all files with
.ndjson extensions in
my-directory/ and its
? to match 1 character Files matching the wildcard
are expected to contain content only, no metadata.
