使用案例

1.1-获取商品

InAppPurchase().getProducts(
    productLists: this._productLists,
    complete: (List<IAPItem> tempArray) {
      setState(() {
        _items = tempArray;
      });
      print(
          'getProducts===>${tempArray.first}');
    },
  );

1.2-渲染商品数据-购买

List<Widget> _renderInApps() {
    List<Widget> widgets = this
        ._items
        .map(
          (item) => FlatButton(
            color: Colors.blueAccent,
            onPressed: () {
              print("---------- Buy Item Button Pressed");
              InAppPurchase().requestPurchase(item: item);
            },
            child: Row(
              children: <Widget>[
                Expanded(
                  child: Container(
                    height: 48.0,
                    alignment: Alignment(-1.0, 0.0),
                    child: Text('Buy-Item${item.title}'),
                  ),
                ),
              ],
            ),
          ),
        )
        .toList();
    return widgets;
  }

1.3 获取购买历史

      (List<PurchasedItem> tempArray) {
    _purchases = tempArray;
    setState(() {});
  });
