To use this plugin on iOS you need to opt-in for the embedded views preview by adding a boolean property to the app's Info.plist file, with the key io.flutter.embedded_views_preview and the value YES.
<key>io.flutter.embedded_views_preview</key>
<true/>
The current Travis script will only print offending files, but won’t fail the build. Added `--set-exit-if-changed` to fix that.
Also, simplified the call from using `grep` and `xargs` to simple `flutter format .`, which recurses directories.
Lastly, fixed offending files that needed `dartfmt`. (But not in the directories that aren’t covered by `travis_script.sh`.
* Add list view to place tracker. Note: map in listTile is not WAI in this commit.
* Remove map from list tiles. Make list tiles tappable (currently editing a place and saving will do nothing if the details screen is pushed from the list view.
* Fix text alignment in list.
* Initial implementation of using an InheritedWidget to maintain data between list and map. Map does not update correctly at this point.
* Use AppModel.update to set the AppState. Add MapConfiguration class to handle map changes based on AppState.
* Don't cache AppState - lookup directly. Extract AppState code into it's own file and add static methods. Address comments from Hans.
* Extract generic AppModel code.
