Matt Perry c13a6e275b Add a maxLines parameter for multiline Input. (#6310)
* Add a maxLines parameter for multiline Input.

If maxLines is 1, it's a single line Input that scrolls horizontally.
Otherwise, overflowed text wraps and scrolls vertically, taking up at
most `maxLines`.

Also fixed scrolling behavior so that the Input scrolls ensuring the
cursor is always visible.

Flutter Examples

This directory contains several examples of using Flutter. Each of these is an individual Dart application package.

To run an example, use flutter run inside that example's directory. See the getting started guide to install the flutter tool.

Tip: To see examples of how to use a specific Flutter framework class, copy and paste a URL with this format in your browser. Replace foo with the classname you are searching for (for example, here's the query for examples of the AppBar class).

Available examples include:

  • Hello, world The hello world app is a basic app that shows the text "hello, world."

  • Flutter gallery The flutter gallery app showcases Flutter's implementation of material design.

  • Layers The layers vignettes show how to use the various layers in the Flutter framework. There is no main.dart in this directory because each file is a standalone example. To run a particular file, use flutter run -t filename.dart.
