## Class SpellCheckChannel

- java.lang.Object
- - io.flutter.embedding.engine.systemchannels.SpellCheckChannel

-     public class SpellCheckChannel
      extends Object

  `SpellCheckChannel` is a platform channel that is used by the framework to initiate spell check in the embedding and for the embedding to send back the results.

  When there is new text to be spell checked, the framework will send to the embedding the message `SpellCheck.initiateSpellCheck` with the `String` locale to spell check with and the `String` of text to spell check as arguments. In response, the `SpellCheckPlugin` will make a call to Android's spell check service to fetch spell check results for the specified text.

  Once the spell check results are received by the `SpellCheckPlugin`, it will send back to the framework the `ArrayList<HashMap<String,Object>>` of spell check results (see `SpellCheckPlugin.onGetSentenceSuggestions(android.view.textservice.SentenceSuggestionsInfo[])` for details). The `SpellCheckPlugin` only handles one request to fetch spell check results at a time; see `SpellCheckPlugin.initiateSpellCheck(java.lang.String, java.lang.String, io.flutter.plugin.common.MethodChannel.Result)` for details.

  `SpellCheckPlugin` implements `SpellCheckChannel.SpellCheckMethodHandler` to initiate spell check. Implement `SpellCheckChannel.SpellCheckMethodHandler` to respond to spell check requests.
