如何在飞镖列表中读取列表（FLUTTER）

Question

final List _icons = [ [ 'IDENTITY', FontAwesomeIcons.camera, ], [ 'SPECIES', FontAwesomeIcons.tree, ], [ 'ARTICLES', FontAwesomeIcons.bookOpen, ], ];

Answer 1

你可以试试

_icons[0][1] //FontAwesomeIcons.camera

但似乎您可以使用map而不是list

final map _icons = { 'IDENTITY' : FontAwesomeIcons.camera, 'SPECIES': FontAwesomeIcons.tree, 'ARTICLES' : FontAwesomeIcons.bookOpen};
_icons['IDENTITY']; //FontAwesomeIcons.camera
