Example

Init Mecab:

var tagger = new Mecab();
await tagger.initFlutter("path/to/your/dictionary/", true);

Set the boolean option in init function to true if you want to get the tokens including features, set it to false if you only want the token surfaces.

Use the tagger to parse text:

var tokens = tagger.parse('にわにわにわにわとりがいる。');
var text = '';

for(var token in tokens) {
  text += token.surface + "\t";
  for(var i = 0; i < token.features.length; i++) {
    text += token.features[i];
    if(i + 1 < token.features.length) {
       text += ",";
    }
  }
  text += "\n";
}
