# element_embedding_demo
|
||||
|
||||
This package contains the application used to demonstrate the
|
||||
upcoming Flutter web feature: "Element Embedding".
|
||||
|
||||
This was first shown on the Flutter Forward event in Nairobi (Kenya), by Tim
|
||||
Sneath. [See the replay here](https://www.youtube.com/watch?v=zKQYGKAe5W8&t=5799s).
|
||||
|
||||
## Running the demo
|
||||
|
||||
The demo is a Flutter web app, so it can be run as:
|
||||
|
||||
```terminal
|
||||
$ flutter run -d chrome
|
||||
```
|
||||
|
||||
## Points of Interest
|
||||
|
||||
* Check the new JS Interop:
|
||||
* Look at `lib/main.dart`, find the `@js.JSExport()` annotation.
|
||||
* Find the JS code that interacts with Dart in `web/js/demo-js-interop.js`.
|
||||
* See how the Flutter web application is embedded into the page now:
|
||||
* Find `hostElement` in `web/index.html`.

SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
|
||||
-----------------------------------------------------------
|
||||
|
||||
PREAMBLE
|
||||
The goals of the Open Font License (OFL) are to stimulate worldwide
|
||||
development of collaborative font projects, to support the font creation
|
||||
efforts of academic and linguistic communities, and to provide a free and
|
||||
open framework in which fonts may be shared and improved in partnership
|
||||
with others.
|
||||
|
||||
The OFL allows the licensed fonts to be used, studied, modified and
|
||||
redistributed freely as long as they are not sold by themselves. The
|
||||
fonts, including any derivative works, can be bundled, embedded,
|
||||
redistributed and/or sold with any software provided that any reserved
|
||||
names are not used by derivative works. The fonts and derivatives,
|
||||
however, cannot be released under any other type of license. The
|
||||
requirement for fonts to remain under this license does not apply
|
||||
to any document created using the fonts or their derivatives.
|
||||
|
||||
DEFINITIONS
|
||||
"Font Software" refers to the set of files released by the Copyright
|
||||
Holder(s) under this license and clearly marked as such. This may
|
||||
include source files, build scripts and documentation.
|
||||
|
||||
"Reserved Font Name" refers to any names specified as such after the
|
||||
copyright statement(s).
|
||||
|
||||
"Original Version" refers to the collection of Font Software components as
|
||||
distributed by the Copyright Holder(s).
|
||||
|
||||
"Modified Version" refers to any derivative made by adding to, deleting,
|
||||
or substituting -- in part or in whole -- any of the components of the
|
||||
Original Version, by changing formats or by porting the Font Software to a
|
||||
new environment.
|
||||
|
||||
"Author" refers to any designer, engineer, programmer, technical
|
||||
writer or other person who contributed to the Font Software.

|
||||
in the appropriate machine-readable metadata fields within text or
|
||||
binary files as long as those fields can be easily viewed by the user.
|
||||
|
||||
3) No Modified Version of the Font Software may use the Reserved Font
|
||||
Name(s) unless explicit written permission is granted by the corresponding
|
||||
Copyright Holder. This restriction only applies to the primary font name as
|
||||
presented to the users.
|
||||
|
