0.4.0 #

• Breaking change. Migrate from the deprecated original Android Support Library to AndroidX. This shouldn't result in any functional changes, but it requires any Android apps using this plugin to also migrate if they're using the original support library.

0.3.2 #

• Adding getWifiName() to obtain current wifi network's SSID.

0.3.1 #

• Updated Gradle tooling to match Android Studio 3.1.2.

0.3.0 #

• Breaking change. Set SDK constraints to match the Flutter beta release.

0.2.1 #

• Fixed warnings from the Dart 2.0 analyzer.
• Simplified and upgraded Android project template to Android SDK 27.
• Updated package description.

0.2.0 #

• Breaking change. Upgraded to Gradle 4.1 and Android Studio Gradle plugin 3.0.1. Older Flutter projects need to upgrade their Gradle setup as well in order to use this version of the plugin. Instructions can be found here.

0.1.1 #

• Add FLT prefix to iOS types.

0.1.0 #

• Breaking API change: Have a Connectivity class instead of a top level function
