flutter - 我的颤振项目运行良好,但现在运行时显示错误
问题描述
我的 Flutter 项目运行良好。我已经实现了谷歌地图,我想在颤动的谷歌地图上绘制源点和目的地点之间的路线。地图也显示出来了。
但是现在当我运行我的代码时,我遇到了错误。请帮我解决这个问题。我现在什至无法运行我的项目。
我得到的错误:

# The following line ensures that the Material Icons font is
# included with your application, so that you can use the icons in
# the material Icons class.
uses-material-design: true
# To add assets to your application, add an assets section, like this:
assets:
- assets/images/sp_screen.png
- assets/images/reg_logo.png
- assets/images/email@_icon.png
- assets/images/mobile_icon.png
- assets/images/arrow_icon.png
- assets/images/Invoice.png
- assets/images/cake.png
- assets/images/calender.png
- assets/images/Reminder.png
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/assets-and-images/#resolution-aware.
# For details regarding adding assets from package dependencies, see
# https://flutter.dev/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
fonts:
- family: Poppins
fonts:
- asset: fonts/Poppins-Medium.ttf
- asset: fonts/Poppins-Regular.ttf
- asset: fonts/Poppins-SemiBold.ttf
- family: Roboto
fonts:
- asset: fonts/Roboto-Medium.ttf
#
# For details regarding fonts from package dependencies,
# see https://flutter.dev/custom-fonts/#from-packages
