flet-dev/flet v1.0.3 on GitHub

Add FletApp.wait_idle(idle_ms, timeout_ms): a host app can wait until an embedded app has rendered its UI and gone quiet - for example before taking a screenshot of it or reading its output after a restart. It returns idle, error (the app failed to start or crashed) or timeout, and costs nothing unless a call is pending (#6901) by @FeodorFitsner.
Add TextField.on_paste_files: pasted files (a screenshot, an image copied from a web page, files copied in the OS file manager) arrive as name, mime_type and bytes, e.g. to attach them to a chat message. On the web it uses the browser's paste event, so it works in every browser, Safari included, with no clipboard permission prompt; on desktop, Ctrl/Cmd+V reports a clipboard image (#6901) by @FeodorFitsner.

Fix Dropdown.expanded_insets having no effect when expand is set (#6895, #6896) by @xsalaices.
Fix Tabs ignoring a new selected_index set together with a new length - e.g. inserting a tab before the selected one and moving selected_index to follow it selected the inserted tab instead (#6901) by @FeodorFitsner.
Fix controls losing their state (a TextField its focus and cursor, a list its scroll position) when a sibling before them in a Column, Row or other multi-child control became visible or hidden: children were matched by position, so the shift rebuilt them. Children are now matched by control id (#6901) by @FeodorFitsner.
Fix FilePicker.upload() with several files uploading the wrong file to each URL: after the first upload, each file's id pointed at the next picked file, so a file's bytes went to another file's URL and the last file never uploaded (its caller waited forever). Picked files now keep their id across upload() calls, and files that can't be found report an upload error (#6901) by @FeodorFitsner.
Fix FletApp.on_error not firing when the embedded app crashes in main() or in an event handler - the error only showed inside the embedded app. The host is now notified, as on_error documents (#6901) by @FeodorFitsner.
