confirmButton method

@override Widget confirmButton(BuildContext context)

It'll pop with AssetPickerProvider.selectedAssets when there are any assets were chosen. 当有资源已选时，点击按钮将把已选资源通过路由返回。

Implementation

@override
Widget confirmButton(BuildContext context) {
  return Consumer<DefaultAssetPickerProvider>(
    builder: (_, DefaultAssetPickerProvider provider, __) {
      return MaterialButton(
        minWidth: provider.isSelectedNotEmpty ? 48 : 20,
        height: appBarItemHeight,
        padding: const EdgeInsets.symmetric(horizontal: 12),
        color: provider.isSelectedNotEmpty ? themeColor : theme.dividerColor,
        shape: RoundedRectangleBorder(
          borderRadius: BorderRadius.circular(3),
        ),
        child: ScaleText(
          provider.isSelectedNotEmpty && !isSingleAssetMode
              ? '${Constants.textDelegate.confirm}'
                  ' (${provider.selectedAssets.length}/${provider.maxAssets})'
              : Constants.textDelegate.confirm,
          style: TextStyle(
            color: provider.isSelectedNotEmpty
                ? theme.textTheme.bodyText1?.color
                : theme.textTheme.caption?.color,
            fontSize: 17,
            fontWeight: FontWeight.normal,
          ),
        ),
        onPressed: () {
          if (provider.isSelectedNotEmpty) {
            Navigator.of(context).maybePop(provider.selectedAssets);
          }
        },
        materialTapTargetSize: MaterialTapTargetSize.shrinkWrap,
      );
    },
  );
}
