如何在应用程序栏右侧添加图标的间距

Question

我刚刚开始拍打，在这里我很困惑如何增加间距。

请帮帮我。

if (Build.VERSION.SDK_INT > Build.VERSION_CODES.N_MR1) {

    Intent shortcutIntent = new Intent(getApplicationContext(), SplashScreen.class);
    shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    shortcutIntent.setAction(Intent.ACTION_MAIN);

    ShortcutInfoCompat shortcut = new ShortcutInfoCompat.Builder(getApplicationContext(), "shortcut")
            .setShortLabel(getResources().getString(R.string.app_name))
            .setIcon(IconCompat.createWithResource(getApplicationContext(), R.mipmap.apt_launcher))
            .setIntent(shortcutIntent)
            .build();
    ShortcutManagerCompat.requestPinShortcut(getApplicationContext(), shortcut, null);
}

使用IconButton代替Icon。

appBar: AppBar(
        title: Text('Breeds of Dogs'),
        automaticallyImplyLeading: false,
        actions: <Widget>[
          IconButton(
              icon: Icon(
                Icons.add_a_photo,
                color: Colors.white,
              ),
              onPressed: () {}),
        ],
      ),
