Flutter libraries incompatibility-CodePudding

I'm working on a flutter project which I'm not the one who developed it first time. After running pub get I have these massive amount of errors:

Because xdg_directories >=0.1.2 <0.2.0-nullsafety.0 depends on process >=3.0.12 <5.0.0 and xdg_directories <0.1.2 depends on process ^3.0.12, xdg_directories <0.2.0-nullsafety.0 requires process >=3.0.12 <5.0.0.
(1) So, because path_provider_linux <0.2.0-nullsafety depends on xdg_directories ^0.1.0, path_provider_linux <0.2.0-nullsafety requires process >=3.0.12 <5.0.0.

    Because process >=4.0.0-nullsafety.1 <4.0.0-nullsafety.4 requires SDK version >=2.10.0-0.0 <2.12.0 and process >=4.0.0-nullsafety.4 <4.0.0 depends on platform ^3.0.0-nullsafety.4, process >=4.0.0-nullsafety.1 <4.0.0 requires platform ^3.0.0-nullsafety.4.
    And because process >=3.0.12 <4.0.0-nullsafety.1 depends on intl >=0.14.0 <0.17.0 and process >=4.0.0 depends on platform ^3.0.0, process >=3.0.12 requires platform ^3.0.0-nullsafety.4 or intl >=0.14.0 <0.17.0.
(2) So, because path_provider_linux <0.2.0-nullsafety requires process >=3.0.12 <5.0.0 (1), path_provider_linux <0.2.0-nullsafety requires platform ^3.0.0-nullsafety.4 or intl >=0.14.0 <0.17.0.

    Because shared_preferences_linux <=0.0.2 depends on path_provider ^1.6.11 and shared_preferences_linux >=0.0.4-nullsafety <2.0.0 depends on shared_preferences_platform_interface ^2.0.0-nullsafety, shared_preferences_linux <0.0.2 1 or >=0.0.4-nullsafety <2.0.0-∞ requires path_provider ^1.6.11 or shared_preferences_platform_interface ^2.0.0-nullsafety.
    And because shared_preferences_linux >=0.0.2 1 <0.0.4-nullsafety depends on path_provider_linux ^0.0.1 and path_provider >=1.6.10 <2.0.0-nullsafety depends on path_provider_linux ^0.0.1, shared_preferences_linux <2.0.0 requires shared_preferences_platform_interface ^2.0.0-nullsafety or path_provider_linux ^0.0.1.
    And because path_provider_linux <0.2.0-nullsafety requires platform ^3.0.0-nullsafety.4 or intl >=0.14.0 <0.17.0 (2), shared_preferences_linux <2.0.0 requires platform ^3.0.0-nullsafety.4 or intl >=0.14.0 <0.17.0 or shared_preferences_platform_interface ^2.0.0-nullsafety.
    And because every version of flutter_localizations from sdk depends on intl 0.17.0 and shared_preferences >=0.5.8 <2.0.0-nullsafety depends on shared_preferences_linux ^0.0.2, if flutter_localizations any from sdk and shared_preferences >=0.5.8 <2.0.0-nullsafety then platform ^3.0.0-nullsafety.4 or shared_preferences_platform_interface ^2.0.0-nullsafety.
    And because shared_preferences >=0.5.4 8 <2.0.0-nullsafety depends on shared_preferences_platform_interface ^1.0.0 and every version of localize_and_translate depends on flutter_localizations any from sdk, if shared_preferences >=0.5.8 <2.0.0-nullsafety and localize_and_translate any then platform ^3.0.0-nullsafety.4.
    And because localize_and_translate ^3.0.3 depends on shared_preferences ^0.5.12 4 and firebase_messaging >=0.2.0 <7.0.2 depends on platform ^2.0.0, localize_and_translate ^3.0.3 is incompatible with firebase_messaging >=0.2.0 <7.0.2.
    So, because educationtqnia depends on both firebase_messaging ^6.0.13 and localize_and_translate ^3.0.3, version solving failed.
pub get failed (1;     So, because educationtqnia depends on both firebase_messaging ^6.0.13 and localize_and_translate ^3.0.3, version solving failed.)
Process finished with exit code 1

This is my pubspec-yaml file:

  # To add assets to your application, add an assets section, like this:

  # 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: Cairo
    fonts:

I tried downgrading the flutter SDK, switching between channels and running changing the libraries version to solve the problem but nothing work. Any ideas how to solve this problem? Thanks.

CodePudding user response：

This problem is very common when Flutter or some plugins have been updated. The only thing that works for me is to update everything, both flutter and the plugins to their latest version and if one is incompatible because it has no maintenance, try to change it for another.

Adding to Miguels answers - you could file issues on the relevant libraries GitHub pages if you need them to be usable on the newest flutter version aswell as compatible with other libraries.
