Add API to allow read data from a specific URI

[alexrintt]

Details

The most recent Android API's, handle the files as a database of URI's, so we can handle it by adding support for cursor queries, as required by #10, thanks @ankitparmar007.

Tasks

• Search and add experimental APIs to allow this usecase.
• Add support for initialUri.
• Add copy API to allow export files.
• Get data dir from a specific app (package id) (Not covered by this package).

Issues

• Avoid using listFiles with large data sets.

Useful resources

• How to list files in an android directory.
• Check query public method API from DocumentProvider class.
• THIS is what I was looking for... maybe. Useful to query a large data set as we can see here.
• Implement initial dir param.
• Remember: Tree Document URI is not Single Document URI.

Snapshot 13 Dec. 2021

News

• Added support for large data sets and removed the API DocumentFile.listFiles due to low performance issue
• Refactor of SAF API: split code into several modules to allow safe and easy refactor and new API implementations
• DocumentFile.listFiles is now an EventChannel since we load all files lazily
• Added support to these DocumentsContract and DocumentFile APIs:

const val GET_DOCUMENT_THUMBNAIL = "getDocumentThumbnail"
const val BUILD_DOCUMENT_URI_USING_TREE = "buildDocumentUriUsingTree"
const val BUILD_DOCUMENT_URI = "buildDocumentUri"
const val BUILD_TREE_DOCUMENT_URI = "buildTreeDocumentUri"

• Added optional argument grantWritePermission to the openDocumentTree API

Missing:

• Support to copy a document to another location
• Support to initialDir of the openDocumentTree API
• Update and improve documentation

_{Even not done yet, I consider a nice progress, I'll try to continue over the week, thanks}

[ankitparmar007]

[alexrintt]

All features mentioned in this issue are available on v0.4.x except by the last one that doesn't make sense for this package.
