Create `SearchBar` and `SearchBarTheme` #122309

QuncCccccc · 2023-03-09T17:30:16Z

This PR is to create a SearchBar widget which is the default trigger for a SearchView.
A SearchAnchor widget will be created soon to show search view.

In order to use the SearchBar with the new Material 3 colors, turn on the useMaterial3 flag in the ThemeData:

  return MaterialApp(
    theme: ThemeData(useMaterial3: true),
    // ...
  );

Related to #117483.

Nice work, just gave it a quick first pass.

Should this file be name search_bar.dart?

Because I think the search bar will only be used for the widget SearchAnchor which will be created in the future PR, so just want to put them in the same file.

I don't know what search anchor refers to, I couldn't find a mention in the guidelines

Sorry for the confusion. To open a search view, I'm creating a SearchAnchor widget so that we can get all the anchor(SearchBar or IconButton or any widget) information, such as size, position and etc. Here's the design doc https://docs.google.com/document/d/1_WOcgddfJ7OyYyaCJhkIWgOYywj2jDeMooFsKg012B4/edit#

Thanks! I'm a bit confused because it talks about the introduction of 2 widgets, and the SearchView section only mentions SearchAnchor. Are these terms used interchangeably and should s/anchor/view/?

If SearchView and SearchAnchor are distinct widgets, is there a way to avoid having 3 public widgets? 2 would be ideal.

I see. I think we will only need SearchBar and SearchAnchor widgets. Will update the design soon! Thanks:)

Should this be in the constructor docs?

Mostly just small stuff. This is looking good.

Do we really want to prevent developers from using 3 or more trailing widgets? Although it's definitely not advisable, it doesn't seem worth asserting if a developer founds a justification for it.

I see. Removed this assertion.

this can be on one line

Fixed this and others! I think the IDE did this kind of format automatically. Sorry for not catching this.

Can you clarify what "the button" is?

Should be "Search bar". Thanks for catching this. Fixed!
